** Description changed: Binary package hint: sudo This is a much less sever bug than bug 761689. Instead of *not* being prompted, and being permanently locked out of sudo, the user is shown a prompt asking what to do about hte differences in sudo configuration, and suggesting they use sudo.d. In the limited case of EC2/UEC images, we can recognize that they're using an unmodified sudo file and appropriately write a sudo.d entry for them. ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: sudo 1.7.4p4-5ubuntu7 ProcVersionSignature: User Name 2.6.38-8.42-virtual 2.6.38.2 Uname: Linux 2.6.38-8-virtual i686 Architecture: i386 Date: Thu Apr 21 21:51:09 2011 Ec2AMI: ami-a6f504cf Ec2AMIManifest: ubuntu-images-us/ubuntu-maverick-10.10-i386-server-20101225.manifest.xml Ec2AvailabilityZone: us-east-1c Ec2InstanceType: m1.small Ec2Kernel: aki-407d9529 Ec2Ramdisk: unavailable ProcEnviron: LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: sudo UpgradeStatus: Upgraded to natty on 2011-04-21 (0 days ago) == natty release note == When upgrading a UEC Image to 11.04 on EC2 or UEC, the user will be prompted regarding changes to local file /etc/sudoers. Selecting "Accept the maintainer's version" will result in the 'ubuntu' user losing access to sudo. Instead, select the default response "keep your currently-installed version" (N). + + == SRU Information == + * Impact: This bug affects upgrade from 10.10 to 11.04 on the "UEC Images" only. UEC Images come with a 'ubuntu' user pre-configured with passwordless sudo access. Upon upgrade of sudo, if the user selects "Accept the Maintainer's version" of the sudoers file, then they will lose sudo access entirely. + * How Bug is addressed: The bug is fixed by modifying the pre-install script of sudo to recognize the particular md5sum of /etc/sudoers that exists in UEC images. If that md5sum is found, then the stock /etc/sudoers file is laid down, and the 'ubuntu user' specific sudoers stanza is written to /etc/sudoers.d/90-cloud-ubuntu . + * Patch: The changes for this fix are available at http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/oneiric/sudo/oneiric/revision/49 . + * Regression Potential: The regression potential here should be *very* low. The only time where different codepath will be taken is if /etc/sudoers has a known md5sum. + * TEST CASE: + * Launch an EC2 instance of 10.10. + * ssh in as 'ubuntu@host' + * enable -proposed + * sudo apt-get update + * sudo do-release-upgrade + * The user will not be prompted for merge of /etc/sudoers + * After upgrade, user still has passwordless sudo access. + * Note: if the fix was not availale (ie, proposed not enabled) then the user will be prompted for merge of /etc/sudoers.
