Looking further in the log files multiple linux-image-4.4* packages are marked for upgrade e.g. "Unpacking linux-image-4.4.0-47-generic (4.4.0-47.68) over (4.4.0-47.68~14.04.1)". However, packages marked for upgrade and not included when calculating the amount of free space needed in boot so we have the following:
2016-11-09 18:57:31,611 DEBUG dir '/boot' needs '0' of '<DistUpgrade.DistUpgradeCache.MyCache.checkFreeSpace.<locals>.FreeSpace object at 0x7fe166fe1be0>' ( 51766272.000000) It's not clear to me if any free space is actually required in boot to upgrade the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640645 Title: subprocess installed post-installation script returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1640645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
