[SOLVED] Where can I find log of checks taking place while booting.

Dear all,
I finally managed to install Archilinux in a Virtualbox Virtual Machine.
Everything seems fine and the OS boots correctly, but when the system is loading I can see that one of the checks performed at boot
returns a FAILED message. The problem is that it is so fast I can't read it.
I also notice a Yellow message but, again I can't read what it is about.

I know it might sound a silly question, but is there a way to se a log of these checks?
Thanks a lot in advance for the help!

Cheers,
Luca

TLDR: all the solutions proposed below are valid (and well worth reading the links for learning purpose). If you just want the list of the failed actions, you can get it with the command

sudo journalctl -b | grep -i failed

Temporarily disable clearing these messages, automatic logging in etc. Extend you scrollback buffer if needed and use Shift+PgUp to view these messages.

Re: [SOLVED] Where can I find log of checks taking place while booting.

Also, look at the output of dmesg and of journalctl

You can start by reading https://wiki.archlinux.org/index.php/Scrollback_buffer

However, heed Karol's warning by reading https://wiki.archlinux.org/index.php/Di … t_Messages

Good luck!

edit: Oh, darn.  Karol beat me to it lol

Re: [SOLVED] Where can I find log of checks taking place while booting.

Thanks a lot everybody. In the end I chose to simply use journalctrl -b | grep -i failed > boot.fails.log to inspect these errors smile more posts arriving to fix the issues.

Re: [SOLVED] Where can I find log of checks taking place while booting.

I think it's important to run this command as root or with sudo.

Re: [SOLVED] Where can I find log of checks taking place while booting.

Ah I didn't know because I did all of this as root (I still haven't setup sudo on my laptop.. I am using Arch to improve my Linux skills, but haven't had too much time to play with it sad)
Thanks for the clarification!

The command should be 'journalctl', like you say in your first post, there's no 'r' :-)

$ journalctl -b | wc -l
13
$ sudo journalctl -b | wc -l
433

As you can see, with sudo you get much more info, although grepping may sometimes return the same results, with or without sudo.
