After installing and restarting my computer from the ubuntu software updater prompt, my computer never completes a boot due to "Failed to start Daemon for power management":

/dev/sda2: recovering journal /dev/sda2: clean, 789912/30498816 files, 66894142/121965056 blocks ^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~^[[20~[FAILED] Failed to start Daemon for power management. See 'systemctl status upower.service' for details.

I tried to go into the grub and boot an older linux version there but the same issue occurred.

Being unable to boot my system, I went into Recovery Menu to attempt to solve issue from there. When I attempted to use "dpkg Repair broken packages" I hit another issue that I did not find talked about in the web:

"Reading cache Can not upgrade An upgrade from 'bionic' to 'focal' is not supported with this tool."

As I keep running into issues pop up I am not really sure what about ubuntu's software update really did to my computer. I am really not sure where to go at this point to address the issues.

  • Hi and welcome. Updated from what to what? Did you read the details in the file like the message told you to? systemctl status upower.service – David Mar 25 '21 at 15:09
  • Hello, I am currently unable to boot up the computer so I do not know how to access systemctl status upower.service. Likewise I was using the automated system updater that ubuntu prompted me with. I believe it was updates to a ubuntu version 20.x – user68703 Mar 25 '21 at 16:08
  • I would have to say re install from scratch with the version you want and forget about an upgrade. – David Mar 25 '21 at 16:12
  • Thank you. I was debating about whether that was the best course of action or not. – user68703 Mar 25 '21 at 16:24

From the log file /var/log/apt/history.log, check that whether systemd:amd64 and systemd-timesyncd:amd64 is removed, if they are you may be effected by https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/1903273

Try installing them sudo apt install systemd:amd64 systemd-timesyncd:amd64

systemd: User daemons fail to start after after update removed snap
