Using discover to install/update repo packages is not safe. It uses packagekit which doesn’t support any form of manual intervention which is often required on Arch. You can easily break your system this way.
Yep, that was missing, I installed, now it works, thanks
I use the terminal most of the time, maybe tkpacman or pamac from the aur, it is only when I do not remember the name of the package, but I remember the icon, I resort to discover / gnome software to have a look for the dang icon, that is just me getting older.
And I use discover to look for themes - icons - cursors when I get bored with the themes.
