I had to dowgrade from LXD 5.21 to 5.20 because I don’t have the right version of ZFS and I can’t upgrade the kernel right now. When downgrading, it will not start because database has been upgraded from version 69 to 73.

I managed to successfully downgrade LXD and the database with the following steps (use with caution):

  1. Check revision of 5.20 version.
snap list lxd --all
Name  Version         Rev    Tracking     Publisher   Notes
lxd   5.21.1-43998c6  28155  5.20/stable  canonical✓  disabled,held
lxd   5.20-f3dd836    27049  5.20/stable  canonical✓  held

  1. Revert to 5.20.
    snap revert lxd --revision 27049

  2. Stop lxd
    snap stop lxd

  3. Backup current database version 73
    cp -a /var/snap/lxd/common/lxd/database/global ~/lxd-db-global-backup-20240411-version73

  4. Restore database version 69

rm /var/snap/lxd/common/lxd/database/global/*
cp -a /var/snap/lxd/common/lxd/database/global.bak/* /var/snap/lxd/common/lxd/database/global/
  1. Start LXD
    snap start lxd
