Re: TeXmacs 2.5.1 Linux/flatpak directory problem

Hello,

	I don't use flatpak [because I compile TexMacs from source]
but I think your problem is caused by the sandboxing done by flatpak.
The following links can probally help in setting the permissions for
the sandbox.

https://www.reddit.com/r/linuxquestions/comments/iivbs9/how_to_allow_flatpa=
k_applications_access_to_a/

https://linuxconfig.org/understanding-flatpak-security-and-permissions

Alternative ypu can try a appimage from texmacs

https://www.texmacs.org/tmweb/download/linux.en.html

Hopes this helps
