ERROR: Error getting passwd structure for user with name

Hi,

I was checking the urbackupclient.log file for one client and noticed that I get these errors every day for all my servers. What is the reason for these errors?
The list contains system users and regular users.

Edit: I have these errors only for Ubuntu 18.04 LTS servers. Those servers where Ubuntu 20.04 LTS is installed doesn’t have these errors.
