[Dennis Tants <address@concealed>]

Hello Robert,

yes our linux manual is somewhat outdated :(
Let me see if I can reproduce the error on my system. Will report later.

But I can assure you, that we had this problem multiple times already. I
mostly remember Linux Mint (around version 18) and Ubuntu (version
16-18) with this problem, thats why I/we came up with the solution of
manually editing the file to match the system user.

But anyway, thank you very much for your time. Will see if I can
reproduce the error.

Best regards,
Dennis
