Thank you for your bug report, and for trying to make Ubuntu better. However, this isn't a bug in any Ubuntu package - rather, one of your configuration files (/etc/apt/sources.list) is not correct, probably as a result of trying to add a 3rd party repository.
You can regenerate a correct source.list file at: <http://www.ubuntu- nl.org/source-o-matic/>. If you have any further problems with this, please open a question at <https://answers.edge.launchpad.net/ubuntu/+addquestion>. ** Changed in: ubuntu Status: New => Invalid -- 'E:Type ‘sudo’ is not known on line 52 in source list /etc/apt/sources.list, E:The list of sources could not be read.' https://bugs.launchpad.net/bugs/155657 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
