Hello 
When I check in connection using ss -tunap - I see short connection after connecting my laptop to internet to - of course - ubuntu servers and... yandex mirror(ip adress from yandex(i don't knkw than Can I write all adress Yandex server x)) and...I dkn't understand why?
This is short connection,after I wrote ss -tunap - I just see TIME-WAIT
Apologise-I worng chexck adress x)
But if it a possible-what will mean?
At Software&Updates you can try to set another server at "download from" if you don't like the Yandex mirror. Usually by default during Zorin installation there are set local mirrors because they often are the fastest and to distribute the server load.
Ok thank you so much
So-this is Yandek's mirror I good understand?
Hello. Did you add any additional repositories ?
Any ppa ?
You can check your source.list ; basically this is a source file who indicate from where Zorin (apt) must take information - there are repositories that can be enable or disable ; but don't touch if you're new in Linux world 
Zorin is based on Ubuntu (and Ubunu is a Debian based distro), so you could find documentation there.
If you want to check without risk you could - i guess - use in a terminal
ls -la /etc/apt/sources.list.d/
("ls" means "list")
and
cat /etc/apt/sources.list
cat > read/show
You also could use the "grep" command.
I am far to be an expert, but as i told you, documentation is there and this could help.
I
No, I don't have any additional ppa
I was check and i see bad x)-this was ubuntu server as I remeber
could you please post a capture - in my case
:slight_smile: cat /etc/apt/sources.list
