LAMP - Mariadb/Mysql installation issue on Debian 5.2.9-kirkwood-tld-1 (no replies)

I was trying to install LAMP server on my Pogoplug V4. All the instructions found on the web for this device is outdated. I successfully passed Apache2, Php 7 working. However, when I try to install Mariadb, I keep on receiving the following error:

I spent the whole day searching for solution on Google/stackexchange etc, but nothing works! I wonder if someone can help me what's the issue? Note that I did the same setup 2/3 days ago on linux lite on my laptop and everything worked without any problem. I am following the instructions found here
