Package mysql-client is not available in raspbian_buster

[Lucas Heijst]

I did a fresh install of raspbian buster on a rpi 3b+

Preparing a fresh install of weewx-4.0.0b13

All with python3 modules.

I got a warning with this step:

# Required if using MySQL:

sudo apt-get install mysql-client

Package mysql-client is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

However the following packages replace it:

mariadb-client-10.0

E: Package 'mysql-client' has no installation candidate

I installed module mariadb-client-10.0 instead without any further errors.

Thanks for the heads up, Luc. I've added it to the TODO list.

Oh, which of the 3 versions of Raspbian Buster did you install? https://www.raspberrypi.org/downloads/raspbian/

• Raspbian Buster with desktop and recommended software
• Raspbian Buster with desktop
• Raspbian Buster Lite.

This sounds like the renaming of mysql that happened a while back.   If they did the mariadb packages correctly they would be set up to 'provide' mariadb-whatever as a capability of their package (I'm speaking from a RedHat background and how RPM does it, I don't know if debian packages can do that or not)

[John Kline]

FWIW, WRT mysql-client, I’m not seeing any difference in buster between Raspbian and standard Debian.  mysql-client does not exist in both cases.

It appears to me that Debian has moved on to mariadb as the drop in replacement.

As for: “ but is referred to by another package.”; perhaps an “apt dist-upgrade” will fix it.

In Buster and Stretch, and probably earlier, there is a meta-package “default-mysql-client” that installs the preferred version of the client, mariadb-client.  In Stretch the mysql-client package still existed but it was just dependent on default-mysql-client so still got the mariadb version.  I don’t have an older system handy to poke around on but I imagine this arrangement existed for several previous versions.  Apparently by Buster, debian expects people to have cleaned up explicit dependencies on the mysql packages.

What about the server side?  It looks like the same thing applies to the mysql-server packge.

It is indeed confusing.  For example, centos8 has:

And just to add more confusion, looks like centos8 has both variants to some extent.  Look where these rpms come from...

Thanks, Les. That simplified things a bit.

Changed the install instructions in commit 937903e
