Improve message error for installing FUSE on Ubuntu

When trying to run AppImages without fuse on Ubuntu this error appears
```
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
for more information
```
Can we do a simple bash script to test if it's ubuntu? Something that does `cat /etc/os-release` and suggests the same as [this](https://askubuntu.com/questions/1363783/cant-run-an-appimage-on-ubuntu-20-04)

Might try to do a PR if the issue is accepted
(IDK if this issue belongs here)
