I'm trying to update mysql on my Debian server with mysq-apt-config, but whenever I try to update it with dpkg -i mysql-apt-config_0.8.11-1_all.deb I get a missing keys error.

> dpkg -i /tmp/mysql-apt-config_0.8.11-1_all.deb
(Reading database ... 54485 files and directories currently installed.)
Preparing to unpack .../mysql-apt-config_0.8.11-1_all.deb ...

Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
key 8C718D3B5072E1F5:

I already have 8.0.3-rc installed, but I want the latest version. How do I solve this?

> mysql --version
mysql  Ver 8.0.3-rc for Linux on x86_64 (MySQL Community Server (GPL))

> lsb_release -a

Add missing key to your key ring :

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 8C718D3B5072E1F5  

And try installation once again:

sudo dpkg -i /path/to/mysql-apt-config*.deb
  • Yes, this didn't work for me, i'm trying to install mysql on a arm system running debian 11. It's a real nightmare.
