Errata

Ignoring TheAssassin/AppImageLauncher/issues/711, x86_64-Qt6_3a746abe447b3c79c5784a7d5622b2ab.AppImage fails to locate QEFIEntryManager via env (due to pkexec):

+ RokeJulianLockhart@Beedell:~$ /home/RokeJulianLockhart/Applications/EFI_Entry_Manager-x86_64-Qt6_3a746abe447b3c79c5784a7d5622b2ab.AppImage
- /usr/bin/AppImageLauncher: /lib64/libcurl.so.4: no version information available (required by /usr/bin/../lib/x86_64-linux-gnu/appimagelauncher/libappimageupdate.so)
+ env: ‘QEFIEntryManager’: No such file or directory

This persists with AppImageLauncher uninstalled, so it's irrelevant; I solely leave it because the original issue contained that error message.

It looks like a missing/wrong dep of the AppImage. Could you also check the libcurl version adn location that you have?

Could you also check the libcurl version

@Inokinoki, I've reproduced this with v0.4.1/QEFI.Entry.Manager.x86_64.AppImage.Qt6.zip, without integrating it with AppImageLauncher this time, to confirm this remains applicable:

RokeJulianLockhart@Beedell:~$ /home/RokeJulianLockhart/Downloads/EFI_Entry_Manager-x86_64-Qt6.AppImage

This kind of dependency management is why I don't understand the allure of AppImage; unlike Flatpak, it doesn't actually abstract much, yet doesn't integrate as a native package would.

adn location that you have?

What does this mean?

Thanks! I just googled that it seems to be just a warning.

Could you try the previous versions to see whether it's a general issue or just this version?

@Inokinoki, it reproduces with v0.4.0/QEFI.Entry.Manager.x86_64.AppImage.Qt6.zip:

Hey @RokeJulianLockhart , I got a few clues - it could be the pkexec command which loses the ENV in the App Image.

As for now, this version (prior to pkexec) could be used. It only misses some refactoring works and i18n. But please remember to run the App Image executable with sudo permission.

I will be working on fixing this. Thanks for the report and investigation!

[roke-julian-lockhart]

It could be the pkexec command, which loses the environment in the AppImage.

@Inokinoki, is that due to a bug in PolicyKit? I ask because, per discuss.kde.org/t/31420/13, I've recently moved to using pkexec (although wasn't for this issue), so would like to ensure that it can't cause similar problems elsewhere, and/or file an upstream report, if you haven't.

As for now, this version (prior to pkexec) could be used.

That indeed works. Thanks!

Not sure, but I modified the code to avoid this, and added the CI to generate AppImage that is not using pkexec as well. In the next release, there should be AppImages as before - it needs sudo ./*.AppImage.

Anyway, I'm also following the related issues in either app image (fuse) or pkexec (PolicyKit) ;)

[Inokinoki]

Attached 2 experimental AppImages in the last release: https://github.com/Inokinoki/QEFIEntryManager/releases/tag/v0.4.1

[roke-julian-lockhart]

@Inokinoki, apologies for the wait. Needed to diagnose AppImage/AppImageKit/issues/1304#issuecomment-3482683017 to ensure I didn't report errors that aren't your fault to you.

Thereafter, all appear to invoke as expected; the pkexec version fails, whereas the version without operates when invoked the superuser:

However, the error that it returns when not invoked as it could be improved:

To empirically confirm:
