[Bug 2019093] Re: ubiquity --no-bootloader crashes trying install to sdb using gpt, swap, efi, and btrfs partition

[Ingo Breßler]

Hello everyone,
I ran into this error too, a while ago. It is caused by the customized btrfs options in the referred guide ( https://mutschler.dev/linux/ubuntu-btrfs-20-04/#step-3-optional-optimize-mount-options-for-ssd-or-nvme-drives ). btrfs was not happy with the *space_cache* option added in the partman config and could not mount the volume. This failure is not forwarded to the ubiquity log. It just finds the mount point not mounted. So, please test the options first, supported options might change with newer/other versions of btrfs/kernels (considering that this guide was for 20.04 and I was installing 23.10 ;)
Best regards!
Ingo
