When troubleshooting issues on a Raspberry Pi sometimes it is helpful to go back and look at the boot log, especially if you are running a headless (no monitor) Raspberry Pi.
Install bootlogd
pi@raspberrypi ~ $ sudo apt-get install bootlogd
You will be asked to restart services, select ‘Yes’. And then reboot your Raspberry Pi
View Boot Log
From now on, if you wish to view the bootlog, you can use the command below to format it correctly;
pi@raspberrypi ~ $
sed 's/\^\[/\o33/g;s/\[1G\[/\[27G\[/' /var/log/bootYou will get the output as shown in the image at the top of this post.

Unfortunately it does not work for me.
#1 During installation I was not asked for a restart! So I did it by sudo reboot now
#2 after restart I tried this:
sed ‘s/\^\[/\o33/g;s/\[1G\[/\[27G\[/’ /var/log/boot
RESULT: (Nothing has been logged yet.)
What has gone wrong, because I made already several reboots?
If I try to reinstall it says that the latest version is already installaed.
I have the same experience. Nothing logged. The file is dated at the time of the last boot. It contains 31 characters.
You have to turn it on with this
sudo gedit /etc/default/bootlogd
now you’ll see a line that says
# Run bootlogd at startup ?
BOOTLOGD_ENABLE=No
change no to yes and save and reboot…..
should now work.
After the first reboot bootlogd to me says:
pi@raspberrypi:/ $ sed ‘s/\^\[/\o33/g;s/\[1G\[/\[27G\[/’ /var/log/boot
sed: -e expression #1, char 1: unknown command: `�’
bash: s/[1G[/[27G[/’: No such file or directory
and this fiel was totally clean :
/etc/default/bootlogd
and I added this line:
BOOTLOGD_ENABLE=Yes
and it till get the same answer, but I don’t know what it mean:
pi@raspberrypi:/ $ sed ‘s/\^\[/\o33/g;s/\[1G\[/\[27G\[/’
sed: -e expression #1, char 1: unknown command: `�’
bash: s/[1G[/[27G[/’: No such file or directory
