Title:
  libunwind-(13/14)-dev conflicts with libunwind-dev

Status in libunwind package in Ubuntu:
  New
Status in llvm-toolchain-14 package in Ubuntu:
  New

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.
