Snapcraft suddenly fails installing build-snaps

snapcraft
1

For my already quite complex Flutter app (Snapcraft config: fluffychat/snap/snapcraft.yaml at main · krille-chan/fluffychat · GitHub) I have a new problem that snapcraft suddenly can’t build it anymore. It fails at the “Installing build-snaps” phase with an error like this:

This does happen on my Ubuntu 24.10 machine but also on the snapcraft build servers which I use via the Github integration. It first started to happen 11 days ago.

While the snap which fails to install is sometimes something different. After a snapcraft clean it is core24, sometimes it is the gnome-46-... platform snap and so on. I have now idea what suddenly causes this. I tried to reset to the last version which was successfully built and the same error occured. So I could maybe assume that a change in snapcraft itself is the actual root cause. I also tried to:

  • Switch back to core22
  • Build without some of the parts, like the zenity-integration
  • Build without the gnome extension
  • snapcraft clean
  • purge and reinstall lxd
  • Try the snapcraft --edge version

I literally have no idea what to do now. The error does not tell me what the next steps could be. Especially when I saw that core24 failed to install. As the error blocks me completely since 11 days (October 23, there doesn’t seem to be a snapcraft update on this date) I fear that the problem doesn’t disappear by itself.

I just checked out v1.22.1 and built it successfully:

What version fails? The tip of git master, or some other branch?

Yes it is the current main branch. However suddenly now there is a different error message on remote build for me:

I don’t know what’s causing the RuntimeError - but I suspect you’re also hitting the issue where snapcraft doesn’t expose errors out to the running machine, but just prints the name of the log file, which is pretty useless in a VM on a remote machine in a datacentre.

I think it’s this bug: Failures when running `snap pack` don't get sent to the user. · Issue #4499 · canonical/snapcraft · GitHub

I’ve tried a lot of different things now:

  • Build with latest version that worked
  • Revert to multiple old versions that worked
  • Make the snapcraft process not build the app at all but build before in github actions and just import the build (also fails with an error message I do not understand: chore: Follow up build snap · krille-chan/fluffychat@56f6f7c · GitHub)
  • Build with core22
  • Locally remove every single package and code and revert to a simple helloworld flutter app (does not build)
  • Locally remove every dependency in the snapcraft.yaml file (also does not build Locally I have a completely different error message than remote which I also do not understand as it seems that random snap dependencies cannot be installed?

So regardless what I try I’m bombarded with absolutely useless error messages which I do not understand. Nothing helps. I cannot build FluffyChat anymore neither remotely, on github actions or on my machine and I don’t know what has ever changed. I’m running out of ideas now. Is there really no one who can point me what to do now?

...

Presumably there is a copy of libelf.so.1 from somewhere that is older than the version in core24 and is missing symbols required by libraries in the gnome-46-2404 platform snap. It’s hard to say more without knowing more about the snap in question.

omg I found it. Thank you so much @jamesh I took a look into the logs and found the plugin desktop_webview_window which is a new transitive dependency, means I have not added it by myself but it came with the upgrade of the flutter_web_auth_2 package to the new version. Looks like this package produces the error you have mentioned it.

Additionally I have a problem that locally I get totally different errors. So when I tried to build the app without any of these dependencies, this masked the actual solution to it. Makes me feel super dump now… I will open an issue at the desktop_webview_window repository and ask for advice there and downgrade the package until a solution has been found. @jamesh thank you so much :partying_face: you saved my day
