[Bug 1912547] Re: cannot install ubuntu on luks btrfs uefi multiboot sda

[VS]

Did some digging, this seems to be the error. But After I checked UEFI version now I am more confused. 
Jan 20 23:35:07 ubuntu /plugininstall.py:   File "/usr/share/ubiquity/plugininstall.py", line 929, in configure_bootloader
Jan 20 23:35:07 ubuntu /plugininstall.py:     "GrubInstaller failed with code %d" % ret)
Jan 20 23:35:07 ubuntu /plugininstall.py: ubiquity.install_misc.InstallStepError: GrubInstaller failed with code 1
Jan 20 23:35:07 ubuntu /plugininstall.py: 
Jan 20 23:35:08 ubuntu partman:   No matching physical volumes found
Jan 20 23:35:08 ubuntu partman:   Reading volume groups from cache.

UEFI/BIOS CHECKER
ubuntu at ubuntu:/mnt/btrfs$ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
UEFI

So I am confused why installer failed when live USB is booting from
grubx64.efi Refind and installation is done on ssd with luks, btrfs,
running pre-existing manjaro os and filesystem. Any help would be
appreciated.
