Krita AppImage Problem

PolishToad · July 19, 2025, 4:55pm

LONG STORY SHORT:

I was using Krita on my Arch Hyprland Installation. There was an Update notification and i tried to update Krita to 5.2.10 but got the error “AppImage Not signed”.

I tried reinstalling Krita, several times. And I always saw the same issue. Either the new Krita wouldn’t open, or it just wont appear in the menu. After some digging I found it might be a “problem with AppImageLauncher” and that i should download Alpha build. I tried to do that but, no luck, since I always got the Cmake Error about version or whatever. SO NOW I’m stuck with Krita’s older 5.2.9 version. I tried installing krita via yay or pacman. Both times, the version was 5.2.11, But the animation part had bugs with moving layers or animation frames.

Could someone please help me with this?

[!WARNING] 5.2.11 has updated the AppImage runtime, which is known to be incompatible with the old versions of AppImageLauncher. Developers of the AppImage runtime suggest to remove or update AppImageLauncher. See this report: Issue 121 More AppImage troubleshooting info is available here: FUSE

YES. This is what I have also found during trying to fix this Mess. Since the Arch Linux package for AppImageLauncher is still without an update. Meaning that I’m stuck with the old krita until they decide to finally release the update. So I’m searching for an alternative way to open the appimage OR different way to get functioning krita. God help me i guess.

OKAY. IM writing this in case anyone else will have the same issue as me.

What you have to do is to build the AppImageLauncher using a master branch for this mess to work:

github.com/TheAssassin/AppImageLauncher

BUILD.md

master

# How to build AppImageLauncher

**Note:** This file was contributed by a user. It may be out of date.

If there are no pre-build binaries for your platform you may consider to build AppImageLauncher yourself. Please follow these instructions.


## Download source

This step is only required if you would like to build the source from GitHub. *If you have a local copy, please skip this section.*

You can download the source either using Git or by mannually downloading a tarball on the [Releases page](https://github.com/TheAssassin/AppImageLauncher/releases).

The branch can be customized by setting the `-b` or `--branch` argument. Select `stable` to download the current stable source or use `master` to get the most current unstable source containing the latest features.

```shell
git clone https://github.com/TheAssassin/AppImageLauncher.git -b stable
cd AppImageLauncher
git submodule update --init --recursive
```

if your doing it on arch linux, the command for downloading the dependencies is like this:

sudo pacman -S make cmake glib2 cairo librsvg fuse libarchive libxpm qt5 curl boost

Then follow the tutorial as usual. HOWEVER, Since Cmake will start to probably give off error versions, you have to add the flag -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to the Cmake Commands

If you get the CMake error during the make command, go find the package that has the problem and find its CMakeLists.txt file and modify the version there to 3.5

After that, you should have this mess working if you follow the BUILD.md

That worked for me.

In my case I uninstalled AppImage launcher because the git version from AUR would not compile for me and I was too lazy to fix it. The issue is that the new AppImage version requires the latest fuse wich “stable” AppImageLauncher is not built with. This is also noted in the patch notes for Krita 5.2.10.

I had the same issue with the git compiler
