[SOLVED] Boots slowly and often fails to boot.

[Jeremy_Ray]

Took several attempts to boot Kubuntu this time. Sometimes, it will do it in one attempt. Here are some error messages -

This one shows up first, and can hang the computer for a minute or two -



After trying for a while, it might produce this message -



Or it might do both -



At this point, I reboot and let it try again. I've had no luck with "Control-D to continue," or "Enter for maintenance," but I may not know enough to make use of those options.

Sounds like a failing hard drive. Have you logged in and done the suggested journalctl -xb?

[Jeremy_Ray]

I just ran it - the output is quite long. What am I looking for?

It may also have been caused by an entry I made in fstab. I've deleted that line - perhaps I'll have better luck next time I reboot.

Very good. That is preferable to a failing hard drive And yes, a dodgy fstab will have that effect but 100% of the time, not every now and then. See if it has helped before we'll check the logs.

It booted on the first go this morning, so that's promising. The flash drive is plenty old though, but in my experience, when a flash drive goes it fails completely and doesn't come back. That's just USB sticks though. The flash drive in my tower is the only flash based hard drive I've owned.

No boot problems since deleting the fstab line.

always use

sudo findmnt --verify --verbose
​

to validate your edit of fstab before you reboot
