This question already has an answer here:
I just created a brand new VM with Ubuntu server 18.04 and took the same steps I did earlier on another server (also a brand new 18.04 installation), but this time while attempting to install the mysql-server 8.0 it was suddenly failing.
The steps I followed were:
wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb
This configured my sources.list to use the 8.0 instead of the 5.x version of mysql.
apt-get install mysql-server, I got:
mysql-server : Depends: mysql-community-server (= 8.0.12-1ubuntu18.04) but it is not going to be installed
Despite having run commands such as
apt-get install -f and
apt-get update several times, and
apt-get upgrade not reporting any held packages, I found this odd. So I tried
apt install mysql-community-server.
Which resulted in the same error, but with missing depends for
apt install libmecab2 it tells me it has no installation candidate, but according to the ubuntu packages website it definitely exists in the repository.
I couldn't see anything out of the ordinary in my
sources.list either, and
apt-get update isn't reporting any errors either.
What could be causing this installation to fail? I took the exact same steps on the physical server, and it worked perfectly on that machine.
