This would indicate a transient issue on the mit mirror. have you tried changing servers in system>administration>software sources?
I have checked the MIT mirror and it works correctly for me at this end using software sources/update manager and apt-get. everything is working correctly so I am going to convert this into a question, if you continue to have problems please respond to the question and someone will help you get it sorted out. ** Changed in: update-manager (Ubuntu) Status: New => Invalid ** bug changed to question: https://answers.launchpad.net/ubuntu/+source/update-manager/+question/37084 -- upgrade error for 8.04 https://bugs.launchpad.net/bugs/242225 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
