The error in the log is: Setting up plymouth (0.8.2-2ubuntu23) ... update-initramfs: deferring update (trigger activated) Killed dpkg: error processing plymouth (--configure): subprocess installed post-installation script returned error exit status 137
This does not indicate a problem with the plymouth package, but that the process was killed externally. A look at dmesg shows that the lzma process was killed with an out-of-memory error: [15910.895238] Out of memory: Kill process 24472 (lzma) score 248 or sacrifice child [15910.895243] Killed process 24472 (lzma) total-vm:381472kB, anon-rss:282432kB, file-rss:856kB And this is not the first process that was killed; before killing lzma, the kernel first had to kill firefox *and* the X server due to lack of memory. I see from the log that you have no swap space enabled. Since your system doesn't appear to have enough memory to run the desktop and do kernel updates without it, it is strongly recommended that you enable a swap partition or swap file. There isn't anything we can do here to reduce the memory requirements of the update, so marking the bug report as invalid. ** Changed in: plymouth (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/787549 Title: package plymouth 0.8.2-2ubuntu23 failed to install/upgrade: subprocess installed post-installation script returned error exit status 137 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
