As mentioned in IRC some formats do not work in Calamares. It would be good to compile a list so that we can A:) Document it. B:) Exclude those from the drop-down list or C:) fix the issue. Further, for the file systems that do not work it would be good to test with another distribution to see if the issue(s) is(are) isolated to (L)Ubuntu.
@svinoba would you be willing to put together a list of what doesn't work?
@kc2bez, we currently have following filesystems in the drop-down list for 'File System' label on 'Create a Partition' window: ext4, ext2, ext3, linuxswap, fat16, fat32, ntfs, reiser, xfs, jfs, unformatted, btrfs, luks, lvm2 pv, luks2, fat12 and minix. Of these, following have issue.
| No. | File System | Issue | Suggestion | |
| 1 | luks | Installer crashes | Remove from the list | |
| 2 | luks2 | Installer crashes | Remove from the list | |
| 3 | lvm2 pv | Installer fails/cannot proceed as no option to create LV. | Remove from the list (at least till LVM issues are fixed upstream) | |
| 4 | fat12 , fat16, fat32 | Installer crashes if selected for system (/) partition. | Provide mount point /dos which gets auto-selected upon selecting these filesystem and mask rest of the normal mount points so user cannot select it for system (/) partition (easier ?). If not, a pop-up window should display informing they have selected incompatible filesystem for the system (/) partition and should not allow installaion to proceed. | |
| 5 | ntfs | Installation completes but when logged in have full access to whole filesystem, can delete, modify whatever and thereby, brick the system. | Provide mount point /windows which gets auto-selected upon selecting this filesystem; rest same as above. | |
Note-1: Regarding luks, although I haven't seen the logs (or able to undestand for that matter), I think what is happening is, the installer encrypts the selected partition (luksFormat), but then does not format the mapped mount point with linux filesystems (luksOpen and /dev/mapper/sda2_crypt steps). Instead, it probably is trying to mount the encrypted partition itself on /target/calamares-root-xxxxxxx rather than the mapped one.
Note-2: Suggestion for fat/ntfs partitions is from Ubiquity (as tested on Xubuntu).
Tested on KaOS (albeit with an older iso - 202011) and confirmed same issues exist there. So, it is not Lubuntu-specific issue.
@svinoba Can you clarify where you're getting your suggestions from? You mention 'Ubiquity' but I just tested in the latest Ubuntu release and I cannot confirm the 'dos' mountpoint or 'windows' mountpoint being autoselected.
@teward, 'autoselect' was probably not correct term as in, it doesn't auto-fill the entry-box. What I meant was the mount point list is auto-updated to show only /dos and /windows options and all other typical options like /, /boot, /home etc are not shown. See attached images (all from Xubuntu, latest daily iso).
If we persist and manually type / for mount point, we get error when we click 'Install Now' saying 'Invalid file system for this mount point' and it does not allow us to proceed. Snapshot attached.
