Hi, I know I have a problem with ipv6 on one machine where ipv6 is enabled but cannot reach outside the local network and ipv4 has a proper working network connection to the outside world.
Trying to get apt (or apt-get) to update results in : Ign:1 http://ftp.nl.debian.org/debian stretch InRelease Ign:2 http://ftp.nl.debian.org/debian stretch-updates InRelease Err:3 http://ftp.nl.debian.org/debian stretch Release Cannot initiate the connection to ftp.nl.debian.org:80 (2001:67c:2564:a120::21). - connect (101: Network is unreachable) [IP: 2001:67c:2564:a120::21 80] Err:4 http://ftp.nl.debian.org/debian stretch-updates Release Cannot initiate the connection to ftp.nl.debian.org:80 (2001:67c:2564:a120::21). - connect (101: Network is unreachable) [IP: 2001:67c:2564:a120::21 80] [...] Etc. How can I force apt and apt-get to use IPv4 to update my Debian softwarem of this machine? Bonno Bloksma
