I'm trying to download Ubuntu Server 17 but the link doesn't work for me.
I'm in Iran and this link that generates for me doesn't work correctly http://mirror.rasanegar.com/ubuntu/cd/17.10/ubuntu-17.10-server-amd64.iso
None of the other mirrors seem to work either.
Ubuntu 17.10 has problems with damaging the BIOS of certain laptops, so it's no longer available and, instead, 17.10.1 was released recently to replace it.
To get the newer version, try downloading the ISO on the main download site or, from the server you were trying to get it from, http://mirror.rasanegar.com/ubuntu/cd/17.10/ubuntu-17.10.1-server-amd64.img (note that ubuntu-17.10 is changed to ubuntu-17.10.1).
