Title:
libunwind-(13/14)-dev conflicts with libunwind-dev
Status in libunwind package in Ubuntu:

Status in llvm-toolchain-14 package in Ubuntu:

Bug description:
Tested on Ubuntu 22.04.
Since these two packages (libunwind-14 and libunwind-dev) conflict
with each other, I cannot install some libraries and tools that depend
on them. For example, I cannot install libc++-14-dev and
libgstreamer1.0-dev together, and that's really unfortunate.
I'm not sure which packages should be somehow fixed (if any), so feel
free to reassign this bug wherever it fits.
