Sorry for my English, I would help many people.
I had cyclic problems for insolvable dependencies.
In this case, I use the procedure given to me by jclvanier.
In terminal root :slight_smile :
Erase all database elements
rm -f /var/lib/rpm/_db*
Recreate database RPM
rpm --rebuilddb
Search for update
urpmi --wget --auto-update
If errors found …, bitte sagen Sie es mir aufrichtig!
