Thanks atom! Indeed, we also had a stale nfs share and an automatic apt-get security update that left our ubuntu 16.04. server in an unclean state since it would silently hang on update-initramfs. Because the mounted nfs share remained unresponsive, update-initramfs was hanging for several days. Killing it and rerunning sudo dpkg --configure -a would result in a deadlock and no other apt-get was possible since dpkg couldn't finish its last operation. Calling update-initramfs manually would also hang and could only be stopped with kill -9 (ctrl+c did not work).
Commenting out the sync command in the generate_initramfs function of /usr/sbin/update-initramfs worked to restore the system to a rebootable state! However a soft shut down didn't work either (shutdown -r now) presumably because it tried to sync the stale nfs mount again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667512 Title: update-initramfs hangs on upgrade, dpkg unusable, unbootable system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1667512/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
