After my i386 Ubuntu 14.04 VM upgraded to 16.04 without problems I decided to do the same with my x64 development VM too.
Downloading packages went fine but during install I got an error that a sysv related packages installer script exited with status 1. (I didn't noted the name unfortunately).
Then the installation proceeded and at a point it started spewing error boxes that many-many packages failed to configure. Then the entire installer bailed out without "too many errors."
When I rebooted the kernel panicked, I cannot boot with the 4.4.0 kernel installed, only the older ones. I managed to boot the system up with older kernel (with (upstart) suffix) and attempted to do a dpkg --configure -a
but the confugrations of every package fails with:
insserv: Script virtuoso-nepomuk is broken: missing end of LSB comment
What can I do to get my system work again? Only a clean install helps now? (after a couple of warnings)
