I’m not agreeing or disagreeing with you, my comment was intended to add the context that might help English readers understand how the natural conclusion they would reach after learning that the app name directly translates to “little red book” isn’t necessarily true.
For me, as an American English speaker the natural conclusion would be that it’s an application designed by maoists in order to discuss Maoism when it’s actually designed for integrated ecommerce.
So go ahead and take a look at your journalctl output. The left hand side should be timestamps, so you can immediately figure out if it’s starting a million years in the past or sometime you know you had the problem.
If it is a million years in the past, use the —since flag and specify the time you want to start at as enumerated in the manual file (man journalctl).
Once you’re looking at the logs in journalctl from a day you know the problem happened, go ahead and use arrow keys and pgup/pgdn to find a reboot. You’ll know when you find a reboot because it’ll look different. The messages will be about figuring out what hardware is attached and changing runlevels and whatnot.
Once you found where the reboot is, go backwards to find something weird happening in the logs.
E: By default the parser (program used to handle text) of journalctls output is “less”. If you want to get out of it, press “q”, and if you want to know more “man less”.
