    It looks like that mirror is down at the moment. I can see the default nginx page when visiting ir.archive.ubuntu.com in a web browser, where I would expect to see the root of the Ubuntu repository. You need to select a different source for your updates.

    It looks like that mirror is down at the moment. I can see the default nginx page when visiting ir.archive.ubuntu.com in a web browser, where I would expect to see the root of the Ubuntu repository. You need to select a different source for your updates.

    It looks like that mirror is down at the moment. I can see the default nginx page when visiting ir.archive.ubuntu.com in a web browser, where I would expect to see the root of the Ubuntu repository. You need to select a different source for your updates.

The Ubuntu country mirror in Iran is down from yesterday.



As you can see it hasn't any output:



curl -Is http://ir.archive.ubuntu.com/ubuntu | head -n 1
HTTP/1.1 404 Not Found


So you can change your mirror to others (like other countries or main server)



For example to change your mirror to main server:



sudo sed -i.bak 's|http://ir.|http://|g' /etc/apt/sources.list
sudo apt update


Or for change to us:



sudo sed -i.bak 's/ir/us/g' /etc/apt/sources.list
sudo apt update



Update: This repository is fixed now and you can use it:



curl -Is http://ir.archive.ubuntu.com/ubuntu/ | head -n 1
HTTP/1.1 200 OK
