Hi everyone, Thanks for all your opinions. I've used the tool with '--force' parameter and it upgraded just fine. Now I'm having some side effects like: "grep: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory" Also, OpenVAS does not boot yet. I'll try a clean install and forget all application-related history. Cheers, Bruno Martins Rumos Services IT Consultant Tel.

The only time the migration process worked for me was on a freshly installed centos6 box, with a minimal install and then upgraded immediately. Admittedly, the only time I ran this was about 6 to 8 months back. When third party repos get involved, all bets are all. Similarly when desktop components and lots of user data is involved, many bets are also off. regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc _______________________________________________ CentOS-devel mailing list CentOS-devel at centos.org https://lists.centos.org/mailman/listinfo/centos-devel
