What to do if gnome-terminal does not start in Ubuntu?

Question

linux

Hello people.

Description of the problem:
The terminal does not start. When I call it in the top panel, it shows that it starts to load and then just disappears. In system monitoring, too, you can’t catch the presence.
I installed temx and there are problems with Cyrillic naturally, and when I execute the ls command, I get something like ''$'\320\222\320...

Also software ubuntu also stopped working a little earlier .

Assumption:

I think that the whole problem in that I thoughtlessly followed the instructions from this site and did not understand anything that was happening.
oss-it dot ru/63
I had to set the windows encoding for the correct output to the console of the c ++ program, but it turned out as it happened.

Actually, I ask you to help me fix the problem with the terminal and encodings, or suggest how you can "roll back" everything without losing data.

PS I tried to reinstall the terminal, all the suggestions on the first links of the search engines too, on the ubuntu forum no one has yet been able to solve such problems (Not counting the encoding changes in the locale file, but this did not help me either)

Answer 1

So.
sudo locale-gen
sudo localectl set-locale LANG=en_US.utf8
reboot system or sudo systemctl restart gdm or sudo service gdm restart

PS The answer was found thanks to one nice person from ubunta chat, thanks to him.

Answer 2

create a new profile (user), go under it and check the operation of the terminal
or open a session as root (this is all in Google)
