Older means what in this context? I guess appimagekit?
Because LM-Studio 0.4 was just released yesterday.

So what's to stop it from being seeded again in Ubuntu desktop? I guess
it's in universe for resolute, but it was in main at least for some
releases.

So maybe by next Ubuntu LTS will be the right time to remove it in
Ubuntu too.

Title:
Should libfuse2 be seeded by default?
Status in ubuntu-meta package in Ubuntu:
New
Bug description:
There is popular software in the ecosystem that is distributed
*solely* as an AppImage for Linux. An example of this is LM-Studio:
https://lmstudio.ai/
When trying to run it, a user is presented with the following:
$ ./Downloads/LM-Studio-0.4.0-18-x64.AppImage
dlopen(): error loading libfuse.so.2
AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE
If I install libfuse2t64 (which provides that) it works just fine.

Of course; the preference would be that lm-studio packages as a Debian
package or Snap, but the reality is there is software that doesn't do
this. To reduce resistance as it pertains to running this kind of
software, I think a pragmatic response is to seed libfuse2t64 as a
Recommends for ubuntu-meta.
