Package: usrmerge Version: 33 Severity: important Dear Maintainer,
I have and debian8-based install with most-but-not-all packages updated to random releases, but the `kbd` package wasn't updated from stretch version 2.0.3-2+b1. Trying to install usrmerge lead to following error message: ``` Setting up usrmerge (33) ... FATAL ERROR: Both /bin/open and /usr/bin/open exist. You can try correcting the errors reported and running again /usr/lib/usrmerge/convert-usrmerge until it will complete without errors. Do not install or update other Debian packages until the program has been run successfully. E: usrmerge failed. ``` I suggest adding conflicts declaration to usrmerge to avoid installing it before kbd is upgraded at least version 2.0.4-4 from buster. I understand that such mixed package updates are discouraged, but really I have tons of modern work&home software installed&working fine and the rule "if apt doesn't show any incompatibilities - it will work fine" - works in 99% cases. This is what makes debian reliable) For the last 1% of a cases a manual intervention is needed. Most of the times I didn't report such oldoldstable incompatibility bugs, but usrmerge is special - its error message explicitly states that I shouldn't update any packages, but manual resolution that I intuitively do - would be updating kbd - exactly the opposite behavior. So its unobvious what to do even for experienced user. Actually after manually executing `sudo apt install kbd` it seems that usrmerge succeeded. ``` Preparing to unpack .../archives/kbd_2.5.1-1_amd64.deb ... Unpacking kbd (2.5.1-1) over (2.0.3-2+b1) ... Setting up usrmerge (33) ... The system has been successfully converted. Setting up kbd (2.5.1-1) ...
