Package: mariadb-client-10.3
Version: 1:10.3.17-0+deb10u1
Severity: important

Dear Maintainer,

On running `innotop`, it appears to work correctly, however upon choosing one 
of the other screens, such as pushing "L" to bring up the lock screen, it 
crashes with the error:
        Use of uninitialized value $text in pattern match (m//) at 
/tmp/innotop.orig line 620.

This is because technically 10.3 is not officially supported by innotop, and so 
it uses old legacy code which returns incorrect results.

While innotop doesn't get support 10.3, us shipping innotop with MariaDB 10.3 
means it should really work with it.  It is substantially close to 10.1/10.2 to 
include it in the ways that works as opposed to using outdated code meant for 
older versions of MySQL.

Ideally, innotop should be updated to include official 10.3 support.  Until the 
developer does that, this will at least make innotop usable on Debian Buster 10.
