I’m trying an in-place upgrade from Centos 7 to Alma 8, which I tried a month ago and was successful. Now I’m attempting it in another environment, but it’s not working and fails with the error shown below.
Running transaction check
Transaction check succeeded.
Running transaction test
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing ‘dnf clean packages’.
