Your assumption is right, this is from the conflict of the old and new libmysqlclient-dev. But then OTOH the newer should upgrade the older and just replace things.
The only thing I wonder is that you have a 14.04 version of that lib and you install the 18.04 version which breaks. LTS upgrades have to be through all LTS releases - so you'd want to upgrade 14.04->16.04->18.04. Some workarounds can not be maintained forever and are dropped in packaging after an LTS due to the assumption above. Maybe such a thing hits you here. But even "that alone" isn't the reason. I tried a trusty->bionic upgrade with that and it worked. root@t:~# apt install libmysqlclient-dev Reading package lists... Done Building dependency tree Reading state information...

For now I'd recommend: - try to make sure the old libmysqlclient-dev upgrades to the new one, worst case remove and re-install it - in general do avoid upgrade paths skipping a LTS release I hope that resolves the issue for you, otherwise you'd need to come back with more data on how you ended up with that old libmysqlclient-dev in the first place - marking incomplete for now until you get back with that (or a success so we can close it immediately). ** Changed in: mysql-5.7 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789975 Title: package libmysqld-dev 5.7.23-0ubuntu0.18.04.1 failed to install/upgrade: trying to overwrite '/usr/lib/x86_64-linux- gnu/libmysqlservices.a', which is also in package libmysqlclient-dev 5.6.41-1ubuntu14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1789975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
