This came to my notice recently.
This particularly applies to recent versions of Ubuntu, it’s flavours, and many of the derivatives, and very particularly to Ubuntu 23.04.
In order to work, an Appimage requires the Fuse (Filesystem in User Space) libraries, and specifically the Fuse2 libraries. 23.04 comes with only Fuse3 libraries by default, and Fuse2 is not included by default.
The fix is however very simple:- sudo apt install libfuse2
There is no need to enable any additional repositories or anything like that, just run that command and the Appimage will launch as desired.
Actually, I am on Kubuntu 23.04 and trying to execute appimage got the following errors:
22.214.171.1242:Sytem.DllNotFoundException: Unable to load shared library ‘libwebkit2gtk-4.0.so.37’ or one of its dependencies. In order to help diagnose loading problems, consider setting LD_DEBUG environment variable: liblibwebkit2gtk-4.0.so.37: cannot open shared object file: No such file or directory
at Eto.GtkSharp.NativeMethods.NMLinux.webkit_web_view_new() and other lines of text that ended with:
at ManagerDesktop.Program.Main(String args) in /home/runner/work/Manager/Manager/ManagerDesktop/Program.cs:line 77
I found your post and terminal output is:
sudo apt install libfuse2
[sudo] password for myviolinsings:

libfuse2 is already the newest version (2.9.9-6).
Any ideas on how to get this running would be much appreciated. TIA
It says it cannot locate any package by that name:
sudo apt install libwebkit2gtk-4.0.so.37
My web search for installing these libraries are mostly 10 yr old posts about ver. 1.0. Most say that 3.0 is included by default on install.
I have searched and only found that the Universe Repo was added in 2020 and that fixed it. But I did add that repo and still AppImage does not work with same errors regarding the libwebkit2gtk. While I have pointed to those files in this discussion, I do not understand how to get them. I was looking for a replacement for QBD, but there are no specific Linux installation guides that would tell me how to get this to work. I guess I will need to keep looking for an app that can be downloaded in Ubuntu format or snap/flatpak form. Thanks.
I was referred here by someone from my topic Blank Window at Startup - Manager Desktop for Linux but I suspect this may be a different problem. But since some of the posts here reference webkit2gtk I thought I’d check and see if related. Latest LinuxMint updates broke Manager and one of them is webkit2gtk. I can roll back latest updates and everything works again. I just posted the complete list of updates that occurred the day it broke Manager on the other thread.
I’m running the latest appimage of Manager - 126.96.36.1993
