Basically title.
I’m wondering if a package manager like flatpak comes with any drawback or negatives. Since it just works on basically any distro. Why isn’t this just the default? It seems very convenient.
There is some drawback. The main one : app can’t communicate with each other.
Example firefox and his extension keepass. As keepass can’t communicate with firefox, you have to open both apps and switch their windows.
You can use flatseal to manage communication between apps but that’s not an easy process and may prove a security issue if you don’t understand the technical jargon.
You only need flatseal on GNOME. KDE has it baked into the settings
Thank for the information. i didn’t know since i use vanilla os :)
Kde has many things baked into the settings that gnome hasn’t. GNOME is just more beautiful (and has PaperWM which is why I have to use GNOME)
Where in KDE are those settings? I see Flatpak permissions listed in Discover (bottom of right panel,) but you can’t change them there. Not sure where else to look. I’ve been using Flatseal but if it isn’t needed …
You can’t change them? https://github.com/KDE/flatpak-kcm

Under the apps section, or just search “flatpak”
can you elaborate on this? I’m on nobara and I had a hard time trying to get flatseal to work for syncthing
I think they’ve actually made progress fixing this specific issue
It was a shitshow when I looked at it a few weeks ago.
to be fair there is a portal, it need to get implemented tho
1- It takes a lot of space. jUsT bUy a bIgGeR dRiVe --stfu I’m not going to spend money for you to waste it
1- a) Everyone assumes you’re an American with 20Gbps symmetrical fiber optic. My internet can’t handle 2+ Gb downloads for a fucking 50 Mb app bro
2- Duplicate graphics drivers. Particularly painful with Nvidia
3- It puts a lot of security work with distro library trees straight into the shitter
4- Horrendously designed system for CLI apps (
flatpak run org.whocares.shit.app)5- Filesystem isolation has many upsides for security but also it can cause some pain (definitely nitpicking)
Where in America is there 20Gbps symmetrical fiber? Everywhere I know tops out at 1gbps if you are lucky that your ISP isn’t shit, and lots of areas are still on slow cable.
In my area my options are 200mbps cable or 100mbps ADSL (which inexplicably costs more than the cable Internet)
Maybe is an hyperbole I have optic fiber straight to my door here and is 10gbps tops but usually it works around 80% of that with some conditions. And it’s not symmetrical I don’t recall the up speed tho.
Lived in 8 different states in the US - never had anything above 1 Gbps. Typically been 300-500 mbps, with only the past and current state state where I’ve gotten 1gbps. Poster is just assuming because we’re a first world country that we have good internet. We don’t. I hear Europe has better speeds than us.
Best I’ve ever had was like 60mbps down. Might be a budget thing though, I refuse to pay more than £30/month for internet
All of this. Plus often it just doesn’t work.
And no. I do not want to blind fiddle with the permissions to fix it.
For me it’s lacking in user friendliness. Go easy on the downvotes if I’m doing it the hard way.
- Flatpaks aren’t really single-executables. You have to use to the
flatpakcommand to run them. - I can’t just say
flatpak run firefox, I have to use the full app-id which could be quite long.
Yes, I could make this simpler with scripts or aliases but how hard would it have been for Flatpak to automatically do this for me?
I’m using KDE and when I download a flatpak it automatically creates a .desktop file. I think gnome does this too if I’m not mistaken. I do have to restart or relogin for it to put the file there but that’s not that bad IMO.
I don’t put anything on my desktop but if I put Firefox in my krunner (alt-f2) box the flatpak shows up right away after installation
I think I’ve been having an issue with the Steam Flatpak where after updating, the .desktop file breaks. If not, my icon is broken for different reasons. Either way, I’ve been running Steam through the command line for ages.
I’m on Endeavour xfce and the .desktop files are just there immediately. I never even knew this wasn’t the case on other systems
I agree, tho trivially solvable with aliases and Desktop app definitions, but still an extra step.

It’s HUGE. That’s the biggest downside for me. I’m always use a deb/native package first because they are way smaller.
Of course they are. they share dependencies with other software. flatpaks bundle all dependencies,which is great for sandboxing,even though some sort of break the rule and share some,they are still sandboxed.
Unless you “firejail” or “bubblewrap” your software, security is much better OOB for flatpaks.
That’s a myth. Security of flatpaks depends entirely on the given permissions, and since most flatpaks just set their own permissions on installation, or require filesystem access to work, there is no meaningful difference in security OOB.
Flatpak apps cannot set their own permissions “on installation”. If flatpak tells you some weather app uses only the network permission then that is all the app is going to get.
For an app to be able to change its own permissions, it first needs permission to the flatpak overrides directory. Any app that does this gets an “Unsafe” designation in gnome-software.
Also about most apps requiring filesystem access to work: I have 41 flatpak apps on my system (Silverblue so everything is flatpak). Only 6 have access to my home or Documents directory. (11 apps requested full filesystem or homedir permission, but 5 of these work perfectly fine after I turned off their permissions in Flatseal).
Notably, “large attack surface” apps like Thunderbird or Firefox don’t have access to my Documents. File uploads and email attachments go through the file picker portals.
Those dependencies adenoid and no kept Upton date, unlike deb/rpm installed stuff. Best sandbox to not compromise your system. Also hope that sandboxing is done right…
The worst part of flatpaks is that they don’t get to see the actual path of files that they open. Instead, they get a /var/run/1000/blah proxy. The proxy is forgotten after you reboot, so any flatpak that memorized that path is holding a bunch of dead links.
- overly verbose way to launch them in terminal
- can sometimess not even respect your gtk/qt theming
- sandboxing/permission system can lead to you trying to figure out which directory you need to give access to when you want to save file if it wasn’t preconfigured
- uses its own libraries and not system libraries, want to play the hit new AAA game with steam flatpak? get fucked it requires a mesa commit that was merged 8 hours a go and you’re stuck on 23.0.4 and can’t use the git release.
Flatpak probably has it’s specific uses like trying to use one piece of proprietary software that you don’t trust and don’t want to give it too much access to your system, or most GUI software clients having an easy way to install Discord on your Steam Deck (no terminal usage, Linux is easy yay), but native packages 99% of the time work better.

Can’t you just install a git snapshot of mesa in a flatpak and use that? Then it’d be an upside
The downside is having to do that manually. Kind of ruins the whole point of it. Flatpaks will remain out-dated until the maintainer has time to push it out. Forever behind.
There’s the
org.freedesktop.Platform.GL{,32}.mesa-gitruntime(?) so that seems wrong. What app always needs the latest snapshot mesa version anyway?According to the example, a hit new AAA title on steam might need it.
That doesn’t mean it constantly requires a mesa git snapshot.
You can, infact there’s outright a mesa git runtime one can add, i don’t imagine too many systems roll so fast as to outpace it https://docs.flatpak.org/en/latest/available-runtimes.html
Startup time and disk space.
It’s great for user apps, gui apps, and sandboxing. It’s terrible for cli apps, libraries, development, and integration.

Some people don’t like it because it uses a bit more storage and can start a bit slower, (I think) they can’t be used for system packages, and I’ve also had some issues with theming
This should be pinned somewhere https://blogs.gnome.org/wjjt/2021/11/24/on-flatpak-disk-usage-and-deduplication/?ref=ypsidanger.com
Edit: the speed shouldn’t be a real issue. You may measure a difference but that’s not an issue as it was with snaps until they improved upon it.
Using flatpak on low end devices (like Linux phones), I can tell you from experience, the speed liss is noticeable. Specially for application startup. As is the resource overhead.
That’s a fairly good point. On mobile startup can be crucial because sessions are short in comparison to desktop where you have longer sessions and startup time is negligable (even the slow startup times of snaps could be ignored for e.g. a video editing session)
Low specs shouldn’t keep the community from moving into newer technology.
Precisely. I’ve been playing with Mobian on a One Plus 6 (works great) and while I really like the idea of using mostly sandboxed app much like things work on Android, right now it certainly negatively impacts the experience.
One thing I always wondered is whether libraries in memory would be duplicated or not. I have seen a lot of people talking about storage space which is cheap and shouldn’t really be the focus for desktops. But I haven’t seen anything about in memory usage.
Good question. With 16 GB RAM 8 haven’t seen RAM issues for normal stuff
Me neither but I if we’re considering having all but the core of the distro in Flatpacks, this policy might mean Linux becoming less accessible to more modest configurations.
Unless Flatpacks deal with it somehow like regular packages do. If two app packages contain the same library within (as opposed to packaged in a dependency), can Flatpack figure out they’re the same and share code memory between the two? For library packages with two apps depending on different versions of the same third party flatpack, does it assume the newer version can be applied to both, optimizing memory usage? If so, wouldn’t that break the premise of flatpacks?
Can I convince my autocorrect that flatpacks and flapjacks are different things?
Inquiring minds want to know.
I think its biggest weakness is also its biggest strength: isolation. Sometimes desktop integration doesn’t work quite right. For instance, the 1password browser extension can’t integrate with the desktop app when you use flatpak firefox.
That’s a good pint actually. A double edged sword for sure!
No proper estimate of download size.
To say nothing of a signed manifest of contents. It’s like 1995-era package management was lost on the kids who built this dreck.
This is one of the biggest annoyances I’ve come across with them for sure.
For me, the question is why I should add an extra layer of complexity. If the things I use already work well using apt, and if most things are bundled in the default distro install, then my life is already good.
This all depends on your software needs, if course. Some people are using a lot of new stuff, so the above setup leads to annoying situations.
Flatpak is a distro on its own, but with original dev support. Its like a Linux Distro replacing others.
So it adds complexity but with the potential to remove it from the OS. For example Libreoffice, Browsers, Thunderbird etc are huge and its a good approach to use official versions here.
Then what’s the point in having different distros lol we don’t have duplication for the sake of duplication there are reasons why there are different distros, philosophies and packaging method. I see this mistake from many usually newer Linux users, there are different distros because there is a point in packaging the OS differently.
Flatpak for example completely abandons makig apps use patched system libraries. Or having different packages for different init systems. Or , god forbid, supporting BSDs
I dont know tbh. Flatpak is a bit like Android apps I think, but those apps only have a single OS to support.
Some developers don’t want to deal with building an app for multiple versions. Sure some DEBs can work without needing to deal with that, but some don’t.
some devs don’t want to debug last arch/ubuntu broken setup.
Indeed.
It ruins single source of truth for apps and their installed state. It hides installed state from standard enterprise tools.
That seems like a shortcoming in those tools, that I’d expect them to fix as Flatpaks are pretty commonplace.
Man I still need to learn a lot of Linux that was Klingon for me.
- no OS level components
- duplicate libraries as some core apps (editor, filemanager, Desktop) cannot be flatpaks (yet?)
- old runtimes etc. dont force developers to keep them updated. Often thats because or 3rd party packagers though
- complicated packaging, I heard that the Flatpak builder is better for certain languages.
- theming issues I heard (on Fedora Kinoite Wayland it just works, and I can also force themes per app)
- bad permissions by default (best we have though)
- bad run commands (this could easily be fixed, and I have a script for it)
For OS components / packaging every part, Snaps may work, but for GUI apps they seem subpar and nobody really cares.
Nix may be way better for installing just anything compartimentalized, but there is no permission system (thats why packaging is easier).
But Flatpaks are really great overall, Bubblewrap, KDE Settings / Flatseal, Portals, official app support. Its really really important.
complicate packaging, XML sucks (are there good editors or something?), I heard that the Flatpak builder is better for certain languages.
What has XML got to do with it? Flatpak manifests are either JSON (not great but OK) or YAML, which is great.
YAML, which is great
countries: - fi - se - no - dk => { "countries": ["fi", "se", false, "dk"] }Weird? One I saw was XML or maybe JSON
Probably JSON. I haven’t been involved in Flatpak for a long time but I’ve never seen XML. JSON is quite close to XML in it’s layout sometimes I find so easily mistaken.
YAML, which is great.
Well, someone had to finally believe that.
I’ve had my first downside with flatpak.
VSCode’s flatpak version won’t let you use certain packages because they’re installed on the system and flatpak is a sandbox with no access. You need to enable some stuff but I’m far too lazy to troubleshoot that shit.
I got the Snap version so I’m ready for the hate.
Yes. That’s quite a downside actually!
In Gajim flatpak too, plugins only can be used if packaged for Flatpak.
I use the ssh plug in to connect with local.
