Note

I have studied other posts about this error, but they didn't help me. So, I'm going to describe my problem here.

Starting MariaDB

Following this guide to install WordPress on an Ubuntu 22.04.5 LTS server. I installed MariaDB and started it:

sudo systemctl restart mariadb.service

Throws failure error. Then sudo journalctl -xeu mariadb.service shows:

/usr/sbin/mariadbd: /usr/local/lib/libstdc++.so.6: version `GLIBCXX_3.4.30' not found

But GLIBCXX_3.4.30 is available

Inspired by this post:

I run strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX and I get:

GLIBCXX_3.4GLIBCXX_3.4.1GLIBCXX_3.4.2GLIBCXX_3.4.3GLIBCXX_3.4.4GLIBCXX_3.4.5GLIBCXX_3.4.6GLIBCXX_3.4.7GLIBCXX_3.4.8GLIBCXX_3.4.9GLIBCXX_3.4.10GLIBCXX_3.4.11GLIBCXX_3.4.12GLIBCXX_3.4.13GLIBCXX_3.4.14GLIBCXX_3.4.15GLIBCXX_3.4.16GLIBCXX_3.4.17GLIBCXX_3.4.18GLIBCXX_3.4.19GLIBCXX_3.4.20GLIBCXX_3.4.21GLIBCXX_3.4.22GLIBCXX_3.4.23GLIBCXX_3.4.24GLIBCXX_3.4.25GLIBCXX_3.4.26GLIBCXX_3.4.27GLIBCXX_3.4.28GLIBCXX_3.4.29GLIBCXX_3.4.30GLIBCXX_DEBUG_MESSAGE_LENGTH

So, GLIBCXX_3.4.30 is actually available.

I run ls -la /usr/lib/x86_64-linux-gnu/libstdc++.so.6 and I get:

/usr/lib/x86_64-linux-gnu/libstdc++.so.6 -> libstdc++.so.6.0.30

Question

Everything looks fine. So, what's the problem?

I expected installing and starting MariaDB to be much more smoother than this :(
