Hi Travis,
do you have an easy reproducer for this?
I'm not familiar with perf, so a step to step guide would help me a lot.

Title:
usrmerge breaks perf symbol lookup

** Tags added: apport-collected eoan
** Description changed:
In 19.10, perf cannot find the symbols for libc even after installing
libc-dbg.
The symbols for libc are in:
/usr/lib/debug/lib/x86_64-linux-gnu/
but libc is in:
/usr/lib/x86_64-linux-gnu/
This is the same issue as:
https://bugs.launchpad.net/ubuntu/+source/valgrind/+bug/1808508
... where the fix was to manually path the Valgrind debug info lookup
path, but this doesn't seem feasible for every application that might
care about symbols. Better to put the symbols in the right place
