After many years of absence, I am trying to get back into soulseek using Nicotine+.
Installed it through Flatpak on a debian based system. Application seems to work fine... except: clicking the "Add" button on the Shares pane of the settings menu does nothing. No dialog opens, no error message is shown, just nothing. Is it a known bug with an easy fix?
EDIT / SOLVED: appearantly when one logs into a remote desktop session, the file picker sometimes crashes. For anyone encountering same issues: login directly instead of remotely, or use suggested solve: https://discussion.fedoraproject.org/t/file-chooser-does-not-open-for-flatpak-applications-f40-sway/126351/4
You need to give Nicotine's flatpak permission to access what you want to share. You can do this easily with Flatseal (another flatpak), select Nicotine+, scroll down and with one tick you can give access to "All user files" (= your /home), or you can add a specific directory if you prefer.
Btw I use the normal version of Nicotine, but this is how it usually works for flatpaks, as a security measure often the flatpak maintainer doesn't set the file access permission automatically.
