I found this is a bug with the current version of systemd and old kernels that are used by some VPS privdes as it is in my case. This bug appears time to time, as we can see on Launchpad: Bug #45234, Bug #1811580; or on ServerFault: Why am I missing /var/run/sshd after every boot?
There are few workarounds of this issue, they all come together to ...

You have 270 not upgraded packages, it is possible there are some dependencies. If you need to keep the current version of some package use sudo apt-mark hold package-name and upgrade the rest. Or find the dependencies that should be upgraded.
On my server certbot was upgraded without any issues, when I've used just sudo apt upgrade.
Based on the OP's ...

GNOME 3 is mostly coded in javascript so an awful lot is done at runtime, and these semi-interpreted languages are memory & resource hogs (though not without some benefits too).
Development in languages like that used in GNOME, or modern windows are faster & easier (with theoretically fewer security concerns as the language provides bounds etc ...

The default PHP version for Ubuntu 16.04 is 7.0. If you want to install a new version of PHP on 16.04 you need to use an additional PPA (as it is shown below) or you must compile it on your own.
My server with Ubuntu 16.04 currently uses PHP 7.2 and there are several operational instances of WordPress and MediaWiki. The web server is Apache 2.4. The ...

Got it.
Removed the PPA's with following command.
sudo ppa-purge ppa:whatever/ppa
After that the do-release-upgrade finished with no errors.
Thank you to @s1mmel and @user535733 for your help.

"New Ubuntu version" there means a new major version, like 16.04 to 16.10 or 16.04 to 18.04. Change it to notify you of a new Ubuntu version never.
Just remember to upgrade Ubuntu before the major version (16.04 in your case) is five years old (three years if you use an Ubuntu flavor, like Xubuntu, rather than regular Ubuntu), because then security updates ...

The problem here is the Ubuntu has taken effected the new group added to your user, so you will need to log out and lo back in to have that change take effect.
So simply log out and back in to solve the permission issue.

I did not find what caused the slowdowns, but I did a manual downgrade to temporarily fix the problem.
I removed the program through Ubuntu Software, and installed it manually using a .deb of a earlier build, which was available on Discord's own website. The slowdowns are completely gone. I have reported the bug to Discord through their own channels.

According to the bug report here, the problem can be worked around by adding the directory creation code to /etc/rc.local.
I've done some research and I still can't figure out what is supposed to create that directory on a normal server startup - there're a couple of scripts under /etc that do this, but they appear to be deprecated as they relate to the old ...

In ubuntu there is the dnss package
From man:
dnss is a daemon that can encapsulate DNS over HTTPS.
It can act as a DNS-to-HTTPS proxy, using https://dns.google.com as a
server or anything implementing the same API.
It can also act as an HTTPS-to-DNS proxy, implementing the same HTTP
API; you can use this instead of https://dns.google.com ...

There is a few different transition technologies which will allow an IPv6-only client to reach an IPv4-only service. I would expect most IPv6-only hosting providers to offer one of those transition solutions in their default configuration. And I believe DNS64+NAT64 is the transition solution most often chosen for this.
You should ask your provider if they ...

Considering no one answered this, I would just like to add that reinstalling it does the trick. I tried 18.04 once again and it seems fine.

Strangely enough, this worked for me:
sudo dpkg-reconfigure tzdata
possible explanation: my cloud provider store time in local timezone (earlier than UTC); at startup MySQL boot first, then NTP, which updates the time to UTC; therefore, MySQL literally 'started in the future'
