ok i did a fast work around but can you while still having the errors paste your /etc/sudoers for me i would liket o compare the 2 files mine with one that errors.
work around = 1. reboot into the recovery kernelthat should give the user root access 2. go to packages.ubuntu.com and download edgys older version 1.6.8p12-1 3. run dpkg -i sudo<tab> 4. reboot into the normal kernel and just ignore the updates unless you use the update-manager -- 1.6.8p12-4ubuntu1 update causes parse errors https://launchpad.net/bugs/51246 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
