Workaround: I'd previously enabled root account so I was able to regain full control over system quite easily via su which does not suffers from issue:
[EMAIL PROTECTED]:~$ su Password: [EMAIL PROTECTED]:/home/sk# echo 127.0.0.1 ath64 >> /etc/hosts This has helped and now sudo resumed operation. However please note: - Usual user does not has root account enabled so I guess the only way in such case is to boot from CD and mount partition.Not what I'm calling easy. - This bug leads to inabilty of updating system or configuring lots of things. Generally, "average Joe" user probably will think his system is done. -- Network update to RC has caused multiple issues with sudo and kdesu (Kubuntu 7.10 x64 -> Kubuntu 8.04 RC x64). https://bugs.launchpad.net/bugs/220843 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
