Please how can I either downgrade?
Or to disable some applications if applications are causing it?
I have solved my problem by manually downloading and going through upgrade process.
Then I found out that only 258 megabytes were left on hard disk.
My guess is that the upgrade could not be finished due to low disk space. Maybe, I don’t know, but maybe the upgrade process is copying all files, or making a copy and if there is not enough free space, there can be a problem.
However, even such situation shall be prevented by making a check in the upgrade process, so that it does not happen. If that was the case.
