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?
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.
Thanks, this is great help indeed. I rarely use flatpak, not very familiar with it. It turns out the home folder was already allowed for Nicotine+, the issue appears to be that Nicotine+ is not allowed to "call" the opening of the dialog box to select the folder to use as shared...
I did not use the bandaid workaround, but instead gained access to the device directly instead of remote desktopping and then the file or folderpicker worked just fine...
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.
