bootchart throws this error message.
sudo pybootchartgui
No path given, trying /var/log/bootchart.tgz
warning: path '/var/log/bootchart.tgz' does not exist, ignoring.
Parse error: empty state: '/var/log/bootchart.tgz' does not contain a valid bootchart
In my version of ubuntu (12.04)
bootchart
creates a different log file every time the computer boots, this goes into the directory/var/log/bootstrap
. Though,bootstartgui
looks by default to the file/var/log/bootchart.tgz
which does not exist.In 12.04, if you install
bootchart
properly, you automatically get an image file of the boot graph representation, so you do not need to runbootstartgui
.In fact, it is enough to run (Alt+F2):
then double click on the image that contains the date and time that you are interested in.
If you want to delete useless logs and save space, you can start nautilus with sudo from the commandline: Type (Alt+Ctrl+T) and then:
This will give you a window where you can also delete files. Be very cautious not to delete anything on another folder!
That error seems to be normal when you installed
pybootchartgui
(is for viewing bootcharts) but did not install packagebootchart
(this makes the bootchart) (source).pybootchartgui
is also used to view other machine's bootchart sobootchart
is not a dependency of this package.Ubuntu 15.04 and later
The boot chart will appear in /run/log/bootchart*.svg with a time stamp in the name.
