Bug Description

OS: Xubuntu 22.04
Desktop Environment: XFCE 4.16
.NET version: 6.0.201 (have also tried 6.0.3)

Issue:
After installing Pinta 2.0.2 from the tarball I am unable to open it in the UI using pinta.desktop but can open it by running pinta in a terminal

Installation steps:
tar -xzf pinta-20.0.2.tar.gz
cd pinta-2.0.2/
./configure
make
sudo make install

What I've tried:

I tried running the following commands as per a few answers on Stack Exchange but no luck:
gio set myapp.desktop metadata::trusted yes
sudo chmod +x pinta.desktop

I also tried marking the Launcher as 'Run in terminal' and changing the command to:
sh -c 'pinta'
sh -c 'dotnet /usr/local/lib/pinta/Pinta.dll'

Does it show up in your UI (e.g. application launcher) and just doesn't run, or is it not being picked up at all?

From https://wiki.archlinux.org/title/desktop_entries#Validation, I'm also not sure if you might need to update the desktop database after doing a manual install

It shows in the application launcher, it just doesn't run. After installing following the steps in my original post it creates the .desktop file in /usr/local/share/applications

I tried running desktop-file-validate on /usr/local/share/applications/desktop.pinta and that seemed to have no effect

I also tried copying the file to my home directory and following the steps in the above link to validate/install the .desktop file to ~/.local/share/applications and update the desktop database and it still doesn't run

Thanks, one other thing to try might be launching the .desktop file from a terminal to see if there's any output (https://wiki.archlinux.org/title/desktop_entries#Run_a_desktop_file_from_a_terminal)

This works - so it would appear the issue is only when running the launcher through the UI

Not sure if this is relevant because every app seems to output this but I get -

(gtk-launch:966773): dbind-WARNING **: 04:01:27.595: Couldn't connect to accessibility bus: Failed to connect to socket /root/.cache/at-spi/bus_0.0: Permission denied

Thanks, that's good to know that it works okay launching the .desktop from a terminal
I think that warning is probably harmless / unrelated
