apt error doesn’t support architecture ‘i386’

On an Ubuntu server, when running “apt update” command, I got the following error message

root@s196379:~# apt update

This error is because the repository do not support i386. To fix the error, edit the file

vi /etc/apt/sources.list

Find

deb https://mirror.rackspace.com/mariadb/repo/10.5/ubuntu focal main

Replace with

Find

deb [arch=amd64] https://mirror.rackspace.com/mariadb/repo/10.5/ubuntu focal main

Solution 2: Remove i386 support

Check your architecture

dpkg --print-architecture

If you are using 64 bit OS, you will see amd64.

Check if multiarch is enabled

dpkg --print-foreign-architectures

If you get “i386”, you have multiarch enabled.

If you don’t have any i386 applications running, you can remove i386 support with

dpkg --remove-architecture i386

If you want to enable i386 support, you can run

dpkg --add-architecture i386

Back to apt

apt error after MariaDB to MySQL change

I have install MariaDB on a Ubuntu 16.04 server. Then installed Virtualmin, that require MySQL, so it removed MariaDB and installed MySQL, this caused apt stop working.

When i run “apt update”, it failed with

root@ok-vm:~# apt upgrade
Reading package lists... Done

Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 mysql-server : Depends: mysql-server-5.7 but it is not installed
E: Unmet dependencies. Try using -f.
root@ok-vm:~#

Next i run ‘apt-get -f install’ as it said in above error message.

That too failed. The error message is

Preparing to unpack …/mysql-server-5.7_5.7.20-0ubuntu0.16.04.1_amd64.deb …
Aborting downgrade from (at least) 10.0 to 5.7.

This is because MySQL detected MairaDB data files in /var/lib/mysql folder, it can’t use same data files as MariaDB is newer version.

To fix the problem, i renamed the folder

mv /var/lib/mysql /var/lib/mysql-old

Now running “apt-get -f install” fixed the problem with apt.

apt-get -f install
