ubuntu 18.04 stopped working after update

had to boot into single user mode – edit the grub entry – add single near the end of the linux line – search single user mode ubuntu 18.04

Then I had to run the first few startup items so that I had a network – update the software and then install lightdm

the list of things to start you can get with ls /etc/rc2.d (leave off the S01 at the beginning).

then start them with systemctl start

systemctl start acpid anacron apf-firewall apport atd avahi-daemon
