As I was running low on space I tried to move my snap to another disk following the answer from Muhammad here: Move snap packages to another location/directory

It broke everything and I cant get it back... I tried running several times the steps to revert but nothing works. Please help me, I am new to Ubuntu and it feels like my system is broken...

This is what I ran initially:

#Stop auto-updating (will *not* crash snaps already open)
sudo systemctl mask snapd.service
sudo systemctl stop snapd.service
sudo systemctl disable snapd.service

#Copy the data
sudo rsync -avzP /var/lib/snapd/  /mnt/EC89002B88FFF246/Ubuntu/snap/snapd/


#Do backups
sudo mv /var/lib/snapd /var/lib/snapd.bak
sudo cp /etc/fstab /etc/fstab.bak


#Change fstab (Change $USER with your name or change the path totally)
echo "/mnt/EC89002B88FFF246/Ubuntu/snap /var/lib/snapd none bind 0 0" | sudo tee -a /etc/fstab


#remount fstab Or reboot.
sudo mkdir /var/lib/snapd
sudo mount -a


if ls  /var/lib/snapd/ | grep snaps
then
    echo "Re-mounting snapd folder is done successfully. !!!!"
    sudo rm -rf /var/lib/snapd.bak
else
    echo "WARNING : Re-mounting snapd folder failed, please revert !!!!! "
    echo "WARNING : Re-mounting snapd folder failed, please revert !!!!! "
    echo "WARNING : Re-mounting snapd folder failed, please revert !!!!! "
    echo "WARNING : Re-mounting snapd folder failed, please revert !!!!! "
    echo "WARNING : Re-mounting snapd folder failed, please revert !!!!! "


# Trying to revert automatically
sudo cp /etc/fstab.bak /etc/fstab

sudo mount -a
sudo umount /var/lib/snapd

sudo mv /var/lib/snapd.bak /var/lib/snapd

echo "Files located at ~/snap/snapd should be removed, but are kept for
recovery until you, manually reboot the system and make sure the service
is running correctly. Then you can manually remove the folder ~/snap/snapd
!!!!!!!!!!!!!!, you should do that manually."

#Restart auto-updating
sudo systemctl unmask snapd.service
sudo systemctl start snapd.service
sudo systemctl reenable snapd.service

I am not expert but it seems like it did not restore properly var/lib/snap: Disk Analyzer output

Please help me

  • At what point did it go wrong, and what was the error message? – Jos Apr 14 '23 at 09:28
  • That link says to move snap apps not the snap environment which you can not do. If you want a stable OS and the quickest fix reinstall. – David Apr 14 '23 at 09:34
  • Is there a way to revert snap and then I would reinstall all the apps I use? Right now, here are the problems:
    • It takes even more storage (probably the backups but I am afraid to delete anything now). I have only 700MB left which was not the case before
    • None of the snap apps work correctly
    • When I boot, I see a bunch of [FAILED] such as core18 (there are many of FAILED). I know that it was a snap-installed app.

  • If I want to reinstall snap from scratch, can I just deletee every folder related to snap and then run: sudo apt update

    sudo apt install snapd

    sudo snap install snap-store

    Are they any necessary files on snap for my system? If not, why do I see some fails when I boot my system?
