Hi everyone and happy new year!
I just ran sudo pacman -Syyu. It found one update manjaro-system-20210101-2 , but the update failed with:

I ran sudo pacman -S manjaro-system and it tried update again, but with the same result. Then I ran the following script again only to make sure that it hasn’t something to do with the mirrors:
#!/bin/bash
sudo pacman-mirrors --api --proto https ftps --method rank --continent
#sudo pacman-mirrors --api --proto https ftps --method rank --country Germanysleep 3
sudo pacman -Syyu
That resulted in: Nothing to do.
Installed is the new version. How do I downgrade to the previous version?
