This was addressed for trusty in bug #1259558. since Ubuntu 12.10 will reach end of life within a few days, I don't believe we will make any further changes to 12.10 for this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1317499 Title: package shim-signed 1.5~12.10.1+0.4-0ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1317499/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
