Public bug reported: I've tried installing "build-essential" package, but couldn't because package dpkg-dev depends on a certain version of libdpkg-perl which is superseeded by the most recent version in the repositories.
After manually downgrading "libdpkg-perl" from 1.18.4ubuntu1.2 to 1.18.4ubuntu1, "dpkg-dev" can be installed and everything is fine. This is a fresh install of Xubuntu 16.04.3 (64bit). No custom modifications of any kind. Just plain-vanilla installation from default repositories (no PPAs, etc). The encountered error message are as follows: The following packages have unmet dependencies: build-essential : Depends: dpkg-dev (>= 1.17.11) but it is not going to be installed The following packages have unmet dependencies: dpkg-dev : Depends: libdpkg-perl (= 1.18.4ubuntu1) but 1.18.4ubuntu1.2 is to be installed Recommends: build-essential but it is not going to be installed Recommends: libalgorithm-merge-perl but it is not going to be installed E: Unable to correct problems, you have held broken packages. Thought you might want to know... Seems to have happened in the past with previous version numbers already: https://askubuntu.com/questions/484750/why-build-essential-failed Thanks in advance.
