Pull request overview
This PR adds the libunwind-20-dev package as an explicit build dependency for stellar-core on Ubuntu Jammy (22.04). This prevents dependency conflicts that occur when libgoogle-perftools-dev automatically pulls in the older libunwind-dev from the main apt mirror, which later conflicts with the newer version from the LLVM repository.
Changes:
- Added
libunwind-20-devto the Build-Depends list in the stellar-core debian control file

Interesting. In PR stellar/stellar-core#5088 we had removed this. |

LG! Noting that the package comes from the llvm-20 repo for jammy, it's not in the Ubuntu archives.

It looks like we need to explicitly add a dependency for
libunwind-20-devfor the tmalloc dependency for jammy. Otherwise, when we go to installlibgoogle-perftools-dev. it will add the olderlibunwind-devfrom the main apt mirror, which later conflicts when we try to get the newlibunwind-devfrom the LLVM repo.
