Whenever I try installing a new package/software using sudo apt-get install and am connected to the internet via my institute LAN, it gives the following error :
Failed to fetch http://fr.archive.ubuntu.com/ubuntu/pool/universe/u/unity-tweak-tool/unity-tweak-tool_0.0.7ubuntu2_all.deb Cannot initiate the connection to fr.archive.ubuntu.com:80 (2001:860:f70a::2). - connect (101: Network is unreachable) [IP: 2001:860:f70a::2 80]



However it works when I am connected via wifi.
Please help regarding this.
Thanks

  • Can you access web sites external to your institution? For example stackoverflow or if you paste that link into the address bar, does it open?

    Can you try the same with the option -o Acquire::ForceIPv4=true added to the apt-get command?
