Hm. The ubuntu2.1 version comes from the security repository, you shouldn't see any dependencies for there, since you haven't enabled those sources (but obviously it's picking them up from somewhere in your sources.list).
Can you uncomment the following lines and try again? deb http://security.ubuntu.com/ubuntu dapper-security main restricted deb-src http://security.ubuntu.com/ubuntu dapper-security main restricted deb http://security.ubuntu.com/ubuntu dapper-security universe deb-src http://security.ubuntu.com/ubuntu dapper-security universe (first, run apt-get update && apt-get upgrade) It's recommended that you enable the security repositories, as your installation may otherwise be at risk of being attacked. -- unmet dependencies https://launchpad.net/bugs/59362 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
