A few comments: You do not want to use linux-image-generic-lts-quantal any longer; it isn't supported. See https://wiki.ubuntu.com/1204_HWE_EOL for details.
Your hardware looks broken: [ 2713.016131] hub 1-0:1.0: over-current condition on port 3 [ 2713.224130] hub 1-0:1.0: over-current condition on port 7 [ 2713.640151] hub 1-0:1.0: over-current condition on port 7 ... Perhaps it is just two usb devices that need to move, perhaps this is a larger problem. Also, your 'rm' command is segfaulting a lot; I suggest checking debsums to see if the on-file 'rm' binary is corrupted. ** Changed in: linux-lts-quantal (Ubuntu) Status: New => Invalid ** Information type changed from Private Security to Public -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1388290 Title: package linux-image-generic-lts-quantal (not installed) failed to install/upgrade: o subprocesso rm cleanup foi morto pelo sinal (Falha de segmentação), core dumped To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-quantal/+bug/1388290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
