Well, there is indeed a bug in the file /var/lib/dpkg/info/linux- image-3.5.0-39-generic.postinst
I substituted all (four) occurrences of pwd in /var/lib/dpkg/info/linux- image-3.2.0-34-generic.postinst with getcwd() and now everything seems to work ... The solution is explained at large @ http://askubuntu.com/questions/233798/linux-image-generic-seems-to-be- broken pwd doesn't work from within perl apparently, it just returns an empty string. In any case, I'm fairly certain that it's a bug that the postinst script calls pwd instead of using Perl's own Cwd like it ought to. pwd is a bash shell command line / bourne shell. Would you please update the linux-image-3.5.0-39-generic.postinst script accordingly ? and the bug status if I couldn't update it. Thanks. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1221138 Title: package linux-image-3.5.0-39-generic 3.5.0-39.60~precise1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 17 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1221138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
