Hi!
Search in the forum SSL certificate error. You'll find several answers. A small summary:
- verify that the packages are not broken
sudo eopkg check
- verify that any pending operation has been completed
sudo eopkg configure-pending
clean
, delete-cache
, rebuild-db
and update-repo
, not really required, but they keep the system clean
I've had the same problem, searching around the forum and using the second command I've found out that the system was still not completely configured from the last update. After running it the problem went away.
Hope it helps!
