I've installed the following packages:
linux-tools-common
, linux-tools-generic
and linux-cloud-tools-generic
I now have perf
but it's a bit broken.
1 –
sudo perf report --gtk
GTK browser requested but could not find libperf-gtk.so
I've opened a bug for the missing library: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1843114
2 –
When running sudo perf report
and opening a function in the TUI I can select Annotate [function-name] but the GUI throws back an error and says
Cannot load tips.txt file, please install perf!
Which looks a lot like this Fedora issue: https://bugzilla.redhat.com/show_bug.cgi?id=1448402
I'd like a fully working perf
. Whats the easiest way to go about getting that? Is there a PPA I should look at? Or building/installing from source?

Regarding:
I had the same issue on Ubuntu 18.04. TL;DR the error message is benign.
The tips.txt file comes from: https://github.com/torvalds/linux/commits/master/tools/perf/Documentation/tips.txt
As described in the original commit the purpose of this file is to show a random usage tip on the help line.
So if you wanted to get rid of the message, copy the appropriate
tips.txt
to/usr/share/doc/perf-tip/tips.txt
.
