I look after a relative's 14.04 xubuntu system. They live some way away so it wasn't possible for me to help them directly. They lost all internet connections, so a) couldn't look for solutions, and b) couldn't do any upgrades. They are capable of following detailed instructions, but don't really understand what they are doing. So when I spell out 'sudo' and they still type 'pseudo' I don't know why it hasn't worked. I'm no expert either, but I can usually sort things out after a time.
Suffice to say this was really hard to resolve. Once I found the askubuntu thread I realised that was probably the cause of their problem, and found this report, but that was only after many other checks and tests. I should stress that they don't have 'proposed' updates enabled (nor even LTS updates), so their system was indeed crippled by an official release, and in a way that made determining a cause and fixing it rather hard. Not great. I got them to try the solution manually enabling eth0, but this didn't seem to work. Eventually I managed to rather painfully describe the method of downgrading the 3 library files (which were very fortunately still in the archives) and that worked. Getting new .debs to them would have been fraught with difficulty. They have since done a full update and all is now well. I've gone to a little length to explain this here because I think the ubuntu family of systems is great, and I encourage non-technical people to use it. Bad updates to network software are, however, very serious indeed, since the means of diagnosing and resolving such issues are inherently unavailable. This doesn't do much for ubuntu's reputation, or its wider use amongst less technical people. Can I hope that 'lessons have been learned'? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539634 Title: network-manager crashes when using libnl-3-200 3.2.21-1ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1539634/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
