Last night my laptop froze up and I had to do a hard shutdown. Now Xubuntu won't boot up. I was getting the error message "mountall: error while loading shared libraries: libply-boot-client.so.2: cannot open shared object file: Input/output error". I tried 'Advanced options for Ubuntu> recovery mode' and selected fsck but received the same error.
I searched for an answer with no success. An old post suggested using a live boot to mount and chroot the partition and update mountall but that didn't work. I now get a blinking cursor when trying to do a normal boot.
I even tried to reinstall plymouth but received a message about breaking it. I was getting the error "plymouth: error while loading shared libraries: libply.so.2: cannot open shared object files: Input/output error" beforehand but that stopped.
