Well I cannot decide now whether this an Ubuntu bug or not. But so far I can help you with this:
Open /etc/apt/sources.list within a text editor with root permissions. If you don't know how let me know. Then add a "#" sign at the beginning of the second line and retry. -- _cache->open() failed, please report. https://bugs.launchpad.net/bugs/120354 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
