I have tried two times and it always fails. According to this little guy debian stopped packaging mysql-client as of buster. I tried to cope with it by installing MariaDB but I struggle to find a useful tutorial. Then I tried with this tutorial but I get the following error when installing the client:
miked@debian:~$ sudo apt install mysql-server
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-community-server (= 5.7.34-1debian10) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
So is it possible to install mysql5.7 on Debian10 buster or should I install a debian9 server?
