Python reminds me of PHP many years ago, when multiple incompatible versions could exist on one server. Do you need another version? The best solution back then was a new server, because any update or installation could break the entire global environment. Half a year after the “Sunsetting Python 2”, major distributions still continue to install Python 2 by default, and it becomes a challenge not to replace the default version after some update or after installing a new package.

Sometimes `apt-get update` fails with a NO_PUBKEY error when the repository public key is missing. Example:

Symptoms: MySQL starts correctly after installation, but fails to start after the first reboot because it cannot create the PID/socket in /var/run/mysqld .

Sometimes after running pip install --upgrade pip , pip fails with the error ImportError: cannot import name main . Here’s the simplest way to fix it.

Setting up a Middleman client API container with Ruby and systemd, plus Nginx configuration for proxying requests.
