[11:12] <dragon_> on boot up I get a message, something like "failed to launch fmdu" or something like that
[11:12] <dragon_> flashes by rather quickly
[11:26] <guiverc> dragon_, I'd suggest switching to text terminal, login & view messages using `sudo dmesg`  (you may want to page the output, and not that'll show all messages including many that plymouth (logo screen) normally hide)
[11:29] <dragon_> could not make sense of it?
[11:30] <dragon_> kauditd_printk_skb: 29 callbacks suppressed
[11:30] <dragon_> ?
[11:46] <guiverc[m]> dragon_: messages can be suppressed (as your paste says) to prevent log events spamming/filling logs & thus actually prevent denial-of-service type attacks... callbacks suppressed is usually not an issue  (~29 doesn't sound malicious)
[11:47] <dragon_> the promt warning I read on boot up is before the lubuntu start up logo, sort of letters on a black screen
[11:47] <dragon_> might not matter much, it boots up and everything runs fine as far as I can notise
[11:48] <dragon_> It appeared after the  04.22 upgrade, and I did that about a month ago I think
[11:48] <dragon_> snap hickups with firefox, minor I think
[11:51] <dragon_> back in a bit, reboot
