Hello, I installed Manjaro KDE minimal yesterday and wanted to activate Flatpak in Pamac as a third party. I executed the following in the terminal:
sudo pacman -S flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
Restart
I was then able to install my desired app from Flathub correctly, but there is still no option to do so in Pamac.
