Documentation needs to be updated for Ubuntu 22.04 / Fuse section

[BobSynfig]

The current instructions are not valid anymore and could lead to break the system.

'libfuse2' can live along fuse3 but we should not attempt to install the package 'fuse' nor to do all the rest with groups/modprobe...

Tested with a fresh 22.04, the only required step is:

sudo apt install libfuse2

If the users follow "blindly" the current instructions, they could think the format is responsible of the damages!

You are referring to this section? https://github.com/AppImage/docs.appimage.org/blob/master/source/user-guide/troubleshooting/fuse.rst#setting-up-fuse-2-x-on-ubuntu-debian-and-their-derivatives

Would you like to send a pull request?

[BobSynfig]

Done https://github.com/AppImage/docs.appimage.org/pull/74

[BobSynfig]

See what I meant? Such "technical review" is bringing only bad image of AppImageKit and the concept of compatibility with older distros is skipped. No "downgrade" to Fuse 2 is required. So yes currently we still need to install a package and can't use them out-of-box on a LiveDVD, but at least the existing AppImages can run until they will work fine with Fuse 3. Just don't install the fuse package!

P.S.: There should be modifications on the Wiki too https://github.com/AppImage/AppImageKit/wiki/FUSE

There is a slight issue with this now. On the latest Ubuntu image, that is, downloaded couple of days ago, it can't locate the package libfuse2.

It's in universe, not sure it's been like that all the time, but it makes sense. You need to enable universe (we should include a hint in the docs, though).

root@e4fa719ae238:/# apt policy libfuse2
libfuse2:
  Installed: (none)
  Candidate: 2.9.9-5ubuntu3
  Version table:
     2.9.9-5ubuntu3 500

Thank you for the quick answer! May it be that universe is enabled by default on installed OS and disabled when running in live mode? Because I am running live USB now for some recovery purposes

[TheAssassin]

I think it is enabled by default for desktop installations only, actually. But I'm not sure. I'm pretty sure it is disabled on live media by default, yeah.
