Thank you for taking the time to report this issue and helping to make
Ubuntu better.
I would validate your media, as errors appear to be related to faulty
media, for example I see the following in your logs
Dec 16 03:21:08 ubuntu kernel: [ 1482.789027] EXT4-fs error (device sdd1):
ext4_validate_block_bitmap:376: comm install.py: bg 96: bad block bitmap
checksum
Dec 16 03:21:08 ubuntu systemd-resolved[1255]: Server returned error NXDOMAIN,
mitigating potential DNS violation DVE-2018-0001, retrying transaction with
reduced feature level UDP.
Dec 16 03:21:08 ubuntu kernel: [ 1482.895669] Aborting journal on device sdd1-8.
Dec 16 03:21:11 ubuntu kernel: [ 1485.899763] EXT4-fs (sdd1): Remounting

Dec 16 03:21:11 ubuntu kernel: [ 1485.899830] EXT4-fs error (device sdd1) in
ext4_do_update_inode:5364: Journal has aborted
I have marked this bug report 'Incomplete' as the problem appears to be
bad media to me, if however you believe I'm in error, please leave a
comment explaining why, and change the status back to "New".
Thanks again for helping make Ubuntu better.
