I tried reinstalling software center (after
apt update) and got errors.
Notice that some Loki Release repositories do not have a Release file.
I upgraded Freya to Loki. I noticed numerous errors in the log about not having permissions, as well as the missing release files in Update Manager.
Here is the syslog output:
