Followup-For: Bug #863675 Control: reopen -1 Control: found -1 1:10.3.12-1 So, which package is shipping /usr/bin/mysql_config ? libmariadb-dev (which got the B+R added) or libmariadb-dev-compat ?
Unpacking libmariadb-dev-compat:amd64 (1:10.3.12-1) ... dpkg: error processing archive /var/cache/apt/archives/libmariadb-dev-compat_1%3a10.3.12-1_amd64.deb (--unpack): trying to overwrite '/usr/bin/mysql_config', which is also in package libmariadbclient-dev 10.1.26-0+deb9u1 Errors were encountered while processing: /var/cache/apt/archives/libmariadb-dev-compat_1%3a10.3.12-1_amd64.deb libmariadb-dev-compat probably needs the same B+R: libmariadbclient-dev (<< 1:10.3) as libmariadb-dev.
