Slow Boot Times & Shutdown Hangs

[Mike365]

I have a Dell AIO running Mint 21.1 with boot and / running on an SSD and Home on another drive. I am using an Nvidia graphics driver.
I have two issues and I'm not sure if they are related. The first is a very slow boot time in the order of 2.5 to 3 minutes.
Below are the results of systemd-analyze, systemd-analyze blame and systemd-analyze critical chain. It appears that the userspace is taking a long time to load.

Startup finished in 15.848s (kernel) + 2min 10.800s (userspace) = 2min 26.648s
graphical.target reached after 2min 10.795s in userspace

The other issue is that when I shut down or reboot, the Mint splash logo appears and then disappears leaving a flashing cursor and it hangs. I have to force a shutdown by pressing the power button.

Any help would be most appreciated.

Make sure you don't have a dvd in the drive, no usb drives, unplug everything
and retry the reboot.
then system-d analyze again
If still slow then post the results of:
blkid
and
cat /etc/fstab

I see a discrepancy---not sure it's a solution.
See this reference from blkid:
/dev/sdb2: UUID="a6e4cf64-620a-44e3-8ab6-01c5e6840cf6" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="0f3d1cf2-7b0d-4f51-9673-7d99c62adf34"
and the fstab statement:
# / was on /dev/sdc2 during installation
UUID=a6e4cf64-620a-44e3-8ab6-01c5e6840cf6 / ext4 errors=remount-ro 0 1

notice sdb drive is referenced as sdc in fstab.

[Mike365]

How do I rectify that?

[all41]

Is there a clone involved?
Same UUID on separate drives

[Mike365]

No clone involved.

It doesn´t matter, it is on commented line and UUIDs are right as per blkid result. It happens, by example, if you remove/unplug a drive or change SATA port after installing. Nothing to do.

Unhide your startup and shutdown messages and see if they give a clue. Look for a countdown timeout running for a process.

Edit /etc/default/grub and remove "quiet splash". Save and run sudo update-grub and reboot

[Mike365]

Hi, Thank you for your reply and my apologies for not acknowledging it as I have been fire fighting other issues. When you say to edit /etc/default/grub do you mean to remove the entire line containing "quiet splash" or just those two words.
Thanks again for your help.

└─home.mount @751ms +40ms

It looks to me that local-fs.target is problematic. This target is responsible for mounts listed in /etc/fstab.

Terminal command lsblk would be more informative than blkid. Please post output of terminal command lsblk -o NAME,FSTYPE,LABEL,SIZE,FSUSED,UUID,MOUNTPOINT,PARTFLAGS.

When posting outputs of terminal commands, please use code display tags and maximize terminal window before executing commands. If you do not know how to do that, please read this tutorial.

It looks that UUIDs for / and /boot partitions in fstab are not correct. Try to change those UUIDs in fstab according to the output of lsblk command.

[Jo-con-Ël]

OP is doing something he does not comment....As per previous blkid fstab was correct but that was a different sdb disk (ID-2: /dev/sdb Samsung model: SSD 860 EVO M.2 1TB, the same on inxi report) than current one (sdb 232.9G).

On previous inxi report the only thing I could mention is half swapfile was in use even RAM was only 30% used.

I did not notice that before. Now I see, the disk sdb in lsblk output is not the same as the disk sdb in inxi output. OP should explain that.
