Had same problem. Got newer rdiff-backup which handles filesystem
problem gracefully and then fixed said filesystem problem.
I discovered that my root cron backup script which uses rdiff-backup had been
failing for months for the same worrysome reason that rdiff-backup had a
problem with a directory it was backing up as root. Confirmed running manually:
.......
File "/usr/lib/python3/dist-packages/rdiff_backup/rpath.py", line 386, in
make_file_dict
statblock = os.lstat(filename)
PermissionError: [Errno 13] Permission denied: b'/home/robert/.cache/doc'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/bin/rdiff-backup", line 32, in <module>
rdiff_backup.Main.error_check_Main(sys.argv[1:])
File "/usr/lib/python3/dist-packages/rdiff_backup/Main.py", line 390, in
error_check_Main
..........
I could not remove the empty directory as the owner or as root. As a
workaround, I got a later version of rdiff-backup which continues
"gracefully" after encountering the above problem.
sudo apt -y install python3-pip python3-setuptools python3-pylibacl
python3-pyxattr
rdiff-backup --version
sudo apt -y remove rdiff-backup
sudo pip3 install rdiff-backup
rdiff-backup --version
rdiff-backup above is in /usr/local/bin
After a few reboots + a manual fsck -V -f on the partition of interest (/home)
which found nothing, rdiff-backup ran clean and I was finally able to remove
the offending directory. I was expecting fsck to have run on the partition of
concern at boot and fixed something but there is no evidence it ran. Only keeps
last boot?

GUI Disk utility says disk is ok probably via smartmon. Will run short
test maually.
