Public bug reported:
I wanted to backup the device my /boot partition is mounted on using
mozilla. But snap prevents me from doing that.
I use fsck here to illustrate what is happening - clonezilla seems to
work when fsck works.
I started by unmounting /boot:
sudo umount /boot/efi
sudo umount /boot
sudo fsck /dev/sda2 # which is the device for /boot
From that I get the error message
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
/dev/sda2 is in use.
e2fsck: Cannot continue, aborting.
My question is: How can I get fsck to run?
The current workaround is:
snap disable all installed snaps
sudo systemctl stop snapd
reboot
Then everything works.
There must be a simpler way of accessing /dev/sda2! It should be
possible to access it without disabling snap.
