Hi Jacob, You appear to be installing old versions of PHP from Ondřej Surý's PPA, and also installing both mysql and mariadb on the same system. For Ubuntu 20.04, we support only PHP 7.4 with mysql 8.0. As you are seeing, mixing mysql and mariadb can cause a lot of conflicts since the two packages provide different versions of the same files.
You may have resolved this issue already, but if not you will probably want to purge all php* and all mysql and mariadb packages, remove the config files and data directories, and start over. If you need mariadb, then do not install any mysql bits; OTOH if you need mysql then avoid installing any mariadb packages. ** Changed in: mysql-8.0 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1929270 Title: package libmysqlclient-dev (not installed) failed to install/upgrade: libmariadb-dev:amd64 1:10.3.29+maria~bionic paketinde de bulunan '/usr/lib/x86_64-linux-gnu/libmysqlservices.a' dosyasının üzerine yazılmaya çalışılıyor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1929270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
