Comment 5 for bug 1923134

Re-attempted install.

Same sda1 partition used (except it's now a Lubuntu hirsute instead of bionic).

Refer new bug report https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1923680 I've marked as duplicate.

The 'out of space' issue I believe is because grub is being written to the installation-media (thumb-drive) and not disk

from other report

ubuntu@ubuntu:/$ df -h |grep target
/dev/sda1 658G 328G 297G 53% /target
/dev/sdb2 4.9M 4.9M 2.0K 100% /target/boot/efi

sdb2 is the installation media; sda is the drive install is being attempted on.
