Bug&Solution: Calamares unmounts all the LVM volumes at the beginning of install 13 April 2022, 12:41:06 I posted this issue at Calamares Github , with steps to reproduce and logs, hopefully it will get resolved. In the meantime, to block the Calamares from unmounting the manually-created LVM volumes, which you may be using as a target for installation (i.e. like in a InstallationWithFullDiskEncryption manual) - you may simply open new Terminal tabs, and in each tab cd to a mount point of LVM volume that you would like to protect from unmounting. In example,Code: [Select]cd /mntandCode: [Select]cd /mnt/bootBelow, I attach the Calamares logs for "failure (unmount not blocked)" VS "success (unmount blocked by cd)", which you could compare 1 Likes
