medium "plf-free" is up-to-date
medium "plf-free_backports" is up-to-date
medium "plf-nonfree" is up-to-date     
medium "plf-nonfree_backports" is up-to-date

Dupa care le-am dat remove si am incercat sa le adaug iar si problema persista, primesc aceias eroare si se adauga doar mediile plf.

Thanks.
