Hi, I can not read a lot of the report as due to the compression some filter seems have to dropped the cyryllic chars to be unreadable. But from what I found anyway is about the conflicting "/usr/share/mysql/errmsg-utf8.txt"
Percona, MariaDB and Mysql are somewhat mutually exclusive forks of the same thing. In your case I assume that you are hit by the fact that they all own that file: $ apt-file search /usr/share/mysql/errmsg-utf8.txt mariadb-server-10.0: /usr/share/mysql/errmsg-utf8.txt mysql-server-5.6: /usr/share/mysql/errmsg-utf8.txt percona-server-server-5.6: /usr/share/mysql/errmsg-utf8.txt percona-xtradb-cluster-server-5.6: /usr/share/mysql/errmsg-utf8.txt Of these only one can be working at any given time. I took a zesty system installed percona-server-server and then mysql-server. And just as I expected on installying mysql the percona would be removed. So in your case some local setup issue is blocking the normal mechanisms to work. Could you outline a few more details and probable he output of: $ dpkg -S /usr/share/mysql/errmsg-utf8.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1687374 Title: package mysql-server-5.7 (not installed) failed to install/upgrade: попытка перезаписать «/usr/share/mysql/errmsg-utf8.txt», который уже имеется в пакете percona-server-common-5.7 5.7.10-3-1.jessie To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1687374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
