I'm using linux for the first time. So please be patient
I'm using Redhat 7.0. When trying to open any rpm file, after doing rpm -i "name of the file" I get the following errors:
cannot get exclusive lock on /var/lib/rpm/Packages
cannot open Packages index using db3 - operation not permitted (1)
cannot open packages database in /var/lib/rpm
Can someone help me, please?
