Failed to start default target: Transaction for.graphical.target/start is destructive

rw flag

enter image description hereI have installed Nvidia drivers then I restarted the laptop.

When I typed exit on root@.. terminal below message appears in red.

Failed to start default target: Transaction for.graphical.target/start is destructive (emergency.target has ‘start’ job queued, but ‘stop’ is included in transaction)

Can I downgrade to default graphic drivers by terminal?

This is probably too late for you, but I just helped a friend with this same issue. The solution was simple. It has to do with a disk not being able to be mounted.

In your case in particular and looking at your included image, I can not see the very first lines that it printed out, which would be helpful--it tells which disk is not able to be mounted.

In my friend's case, in the /etc/fstab file, there was an extra entry for an external USB hard drive. For some reason, the system wasn't able to find it at boot, and it caused this same draconian message that you're getting.

The solution was simply to edit the file (sudo nano /etc/fstab) and put a # at the start of the relevant line to prevent the line from being active. Reboot and computer started up normally.

This whole thing happened when updating Kubuntu 20.04 to 22.04.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
