Hi, @mickee (Brian Bogdan).
Let me try to help you here :
1 - Run the following command to see if the UUID of the "EFI" partition matches the UUID that you have in your "/etc/fstab" for the "/boot/efi" mount point:
lsblk --fs | grep -i 'efi'
2 - Run the following comand to see if the UUID for the "/" mount point matches the one you have in your "/etc/fstab" for that same mount point (in all likelihood it will match or else the system almost certainly would NOT boot at all!):
blkid info $(df -h | grep --regexp '/$' | awk '{ print $1 }')
3 - Run the following command to see what swap devices are being used:
swapon --show
For other people reading this: when @mickee mentions "the issue "A job taking 1:30 minutes from boot time" (From Dec 2020)" he is referring to the following Topic here in the "Ubuntu MATE Community":
