"Printing troubleshooter" wizard on one step offers to collect information from journalctl and produces a command which it offers to copy and execute from CLI. Here it is: su -c 'journalctl -u cups.service --since="None" --until="2018-12-16 19:50:37"' > troubleshoot-logs.txt (Of course, date in "--until" will be different). However "journalctl --since=" does not accept "None" as an option.
Where is this option?
(In reply to Julien Nabet from comment #1) > Where is this option? In "Printing troubleshooter" wizard. This is connected to another bug that I reported: https://bugs.documentfoundation.org/show_bug.cgi?id=122142. Repeat the steps to reproduce the bug. After them appears "Print error" window with buttons "OK" and "Diagnose". (Note: this window doesn't always appear, you may have to send another document to the printer). Click "Diagnose". "Printing troubleshooter" wizard pops up. Forward -> select the printer -> Forward -> Print test page -> No -> Forward. Here the wizard says "No journal entries were found" and offers a command to copy and execute in CLI. This command is: su -c 'journalctl -u cups.service --since="None" --until="2018-12-16 19:50:37"' > troubleshoot-logs.txt See --since="None" The result of running this command is: Failed to parse timestamp: None The man page of journalctl also makes no mention of the option "none" in the section "--since".
I don't know any "Printing troubleshooter" wizard on LO so can't help here.
@Caolán, do you know anything about this printing thoubleshoorter wizard ?
I imagine its https://fedoraproject.org/wiki/How_to_debug_printing_problems#Printing_troubleshooter (or something similar) and it belongs to the underlying OS, rather that a specific libreoffice thing
