Comment 7 for bug 1828166

Hi, perf should be in package linux-tools-common and each kernel versions has a dedicated linux-tool-common) package version.
$ dpkg -S $(which perf)
linux-tools-common: /usr/bin/perf
But on disk it's usually in /usr/bin.

Please can you check if it's in with:
$ dpkg -L linux-tools-common | grep perf$
/usr/bin/perf

In case it's not can you just take it temporarily from the last recent bionic package?
wget http://launchpadlibrarian.net/417515745/linux-tools-common_4.15.0-48.51_all.deb
dpkg-deb -x ./linux-tools-common_4.15.0-48.51_all.deb
I think that would be okay for this pre-test, since the perf tool wasn't touched, but just the kernel.

The verification during the SRU process later of course needs to be with the proper package.
