I've kept my 16.04 lts consistently updated and chose to upgrade today to 18.04 lts.
I followed instructions within 16.04 and was still able to use the computer until it was ready to reboot with 18.04 lts. I was hoping this would work rather than a fresh installation since I wish to keep my files and folders.
After passing the BIOS I had my usual choices of *Ubuntu, Advanced Options and Win 10 (It is a dual boot set up machine). Then white writing on black appeared (see image 1): 2 ACPI errors [CAPD] and another
The dark purple/black screen appeared with 18.04 and the dots. Then came flashing a message, that...Gave up waiting for suspended/ resume d ervice: /dev/sdc1: clean, 467342/16580608 files, 10722236/66302208 blocks (see image 2)
There is nothing further, it stops flashing. So I switched off and tried Advanced options..
Using the advanced option 4.1.15 0-30 (recovery mode), it failed, but everything ok'd i chose then a normal boot, again all ok'd, except [FAILED]-Failed to start Samba NMB Daemon. See 'systemc1 status nmdb.service' for details. Further down says [OK] started Samba SMB Daemon. (however..) And the PC remains in this mode unbooted at the last entry [OK] Started Update UTMP about system Runlevel Changes until turned off
What can I do other than do a fresh install from a DVD? The machine will not boot Ubuntu now.
