Alex, you can hold a package to avoid upgrading it with aptitude (and apt-get I suppose)
In example, if you don't want to upgrade beryl, type: # sudo aptitude hold beryl Remember, when you want to upgrade it you can unhold it and upgrade OR just install it: # sudo aptitude unhold beryl # sudo aptitude install beryl To know if there is a newer version, you can check your system's version and the repo's one with: $ apt-cache policy beryl -- beryl-xgl missing from beryl and beryl-core (feisty) https://bugs.launchpad.net/bugs/95394 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
