If you are an older TROMjaro user and did not yet implemented the Chaoric AUR into your system, we highly recommend you to do that. Our Library of apps also relies on it. It is super easy to implement.
You will be asked for your password and such.
sudo pacman-key --recv-key FBA220DFC880C036 --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key FBA220DFC880C036
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-keyring.pkg.tar.zst' 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'
Go to the file
/etc/pacman.conf, open as root (right click the file), and at the very bottom of it (very important) add this:
[chaotic-aur] Include = /etc/pacman.d/chaotic-mirrorlist
Open Add/Remove Software.
Refresh your database:
Close Add/Remove Software, Open again. Then check to see if you can access the repository. For example if you search for Ungoogled Chromium you should be able to find it in Repositories.
If not try to do this command in the terminal:
sudo pacman-key --populate chaotic
That’s all! Enjoy!
