[Bug 241305] Re: security.ubuntu.com not accessible in IPv6 (AAAA record missing in the DNS)
** Description changed: Dear, The apt source list for security update is by default configured to security.ubuntu.com. When you have a system using only IPv6 (and having not access to IPv4 via NAT-PT), - security.ubuntu.com is only reachable in IPv4. + security.ubuntu.com is only reachable in IPv4. It would be wise to configure an record to security.ubuntu.com to at least point to one of the many mirrors supporting IPv6 connectivity. That would avoid system running natively in IPv6 to lack by default the security update. Thanks a lot, Kind regards PS : I checked this as being a security vulnerability but this is more a configuration issue on the Ubuntu network infrastructure than a real security vulnerability: - A DNS request : - dig -t security.ubuntu.com ; <<>> DiG 9.4.1-P1 <<>> -t security.ubuntu.com ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 26872 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;security.ubuntu.com.

[Bug 447181] Re: [xorg-edgers] Video driver error: No kernel modesetting driver detected
Well i`ve got this issue too (Acer TravelMate 2353, 2.6.28-15 and xorg-edgers intel drivers). Why don`t you post an instruction on how to downgrade to the version of the xserver-xorg-video-intel which is not affected by this bug? At least as a temporary workaround for those who don't want to upgrade the kernel. (As for me, I don't want to upgrade the kernel because of the WiFi problems) Thanks in advance :) -- [xorg-edgers] Video driver error: No kernel modesetting driver detected https://bugs.launchpad.net/bugs/447181 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
