Hello. Around 2 days ago I noticed an issue in using apt update:

They have been ignored, or old ones used instead. Apparently, it is failing to connect because of some IPv6 issues. I do not know yet what could be causing the problem, but I am using Turk Telekom (Turkey's largest ISP) for my Fiber Internet and I can't install or update packages because of this. I can browse launchpad.net and ppa.launchpad.net URLs from my browser just fine. Weirdly enough this issue just poped-up two days ago, without any action from my side. I checked my router's and system settings and IPv6 is enabled. However, some people say that Turk Telekom does not support IPv6, so I am not sure about the situation or what can we do from here to check the problem. Any help would be appreciated. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-users Post to : launchpad-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-users More help : https://help.launchpad.net/ListHelp
