Pinta 2.2.1 on Ubuntu 20.04.6 LTS
( happens with 'save' and 'save as'

This might be the same as bug 2024171. Are you running Pinta from a sandboxed environment (snap / flatpak) and saving to a location outside your user directory?

[Eric Beversluis (ubuntueb)]

Thanks for your reply, Cameron.

I don't know if it's running from snap or not. I'm fairly new to Ubuntu
and didn't think of snap as a "sandboxed" environment. How would that
affect saving to a sub-directory under /home/eric?

Is there a fix or work-around?

Should I uninstall the version I have and use apt to install Pinta?

Thanks.

I think if you run `snap list` from a terminal that should show you the packages you have installed there.
The issue is more likely to be if the file is not under your home directory, e.g. the /tmp/ folder, which may not necessarily be included in the default permissions for the sandbox.
Is the file you're saving under your home folder?

[Eric Beversluis (ubuntueb)]

It's in a sub-dir of the home folder, /home/pictures-linux

I've gone ahead and re-installed via apt.

Thanks.
