since one year I use urbackup for my home network for 10 computers, half Linux, half Windows. Started on a RasPi2b with Ubuntu Server 18.04 LTS, updated two monthes ago to Ubuntu Server 20.04 LTS without any problem.
Once a month I have to restart the PasPi, caused by the unattended updates, which requires sometimes a reboot.
After last of such reboots at 17. Oct. i got for all clients the same error:
Creating empty filesystem failed (Server error) "ERROR: target path already exists: /backup/urbackup/<Client_Name>/201023-0800
Backup had an early error. Deleting partial backup.
The output of urbackup_snapshot_helper test is:
Testing for btrfs…
Create subvolume ‘/backup/urbackup/testA54hj5luZtlorr494/A’

UrBackup Server is 2.4.13,
Urbackup clients are 2.4.8, 2.4.9 and 2.4.10.
More than 2000 backups are ok, now this.
Has anyone any hint for me, what change has happen through the unattended updates whithin the last month?
Thanks in advance.
