Thank you for taking the time to report this issue and helping to make Ubuntu better.
This installation looks like it was caused by a corrupted file system, or device problems (sda1). I notice in the logs Dec 7 11:19:51 ubuntu kernel: [ 720.753542] EXT4-fs error (device sda5): __ext4_find_entry:1541: inode #5767494: comm mktemp: checksumming directory block 0 Dec 7 11:19:51 ubuntu ubiquity: mktemp: failed to create directory via template ‘/var/tmp/mkinitramfs_XXXXXX’: Bad message#015 Dec 7 11:19:51 ubuntu ubiquity: rm: cannot remove '/boot/initrd.img-5.4.0-42-generic.dpkg-bak': Read-only file system#015 Dec 7 11:19:51 ubuntu ubiquity: dpkg: error processing package initramfs-tools (--configure):#015 Dec 7 11:19:51 ubuntu ubiquity: installed initramfs-tools package post-installation script subprocess returned error exit status 1#015 Dec 7 11:19:51 ubuntu kernel: [ 720.754275] Aborting journal on device sda5-8.

I suggest you validate the health of your hardware (esp. disk by checking it's SMART status using `smartctl`, `gnome-disks` or whichever tool you prefer), and possibly the integrity of your partition table.
