@vmsman @Daniil
I ran into the same problems with 5.0
It’s still not a real dark theme which is higly appreciated but i found that this version of the script is working:
they also seem to try to keep up to date with version changes.
5.0.2 which i use works with it, altough its not mentioned on github yet.
hope this helps.

Thanks @mathias. So, this is really interesting. I was using this script in 5.0 and it was not working. It was sort of 50/50 light dark. I too updated to 5.02 a couple days ago. Magically the script I had been using and the one you reference just started working properly again. Yay! Will wonders never cease? Thanks for the heads up.
i also had 50/50 light dark but with an older script. i think they keep it up to date on github so it makes sense to check each time it breaks with a new version. however maybe also between 5.0 and 5.02 there is a change in rc but this is unlikely i guess? however good that it works for you 
Sadly, dark theme has broken with RocketChat 5.3 again. It looks okay, but the message line where you type is black on black. Anyone else have a fix?
Same issue here, upgrading broke the dark mode for my users, which is not an expected behaviour when running an upgrade.
After a quick digging, we found out that we had to add the --message-box-color variable to fix the aforementioned bug at the beginning of the body.dark-mode class definition.
--message-box-color: var(--color-white);
@rhapsodos that solution rocked! Thanks for that. Worked like a charm. Have you noticed that the title bar at the top of a channel is also this bright white in this version?
Wow, commercial software not implementing for-years-requested features. Ridiculous.
So dear RocketChat developers: Please add an actual dark theme that users can toggle themselves,
this is actually a accessibility setting that helps impaired people to use a product properly.
Watch out for v6 of Rocket.Chat that is going to be released in the near future, I have seen designs and talk of an official dark theme! 
I’m new to rocket chat and was disappointed because it doesn’t have dark theme, but it is here. Probably it is the v6 mentioned in previous comment.
Hello there!
Is it possible for me to update a cloud instance to v6?
Do you know if there is a way to change the sidebar correspondend to the selected mode?
Because it’s also dark for me if I select the light mode.
