** Description changed: [impact] A simple typo using the update-locale script can render a system inoperable without booting into single user mode or similar: $ sudo update-locale LANGUAGE = en_US.UTF-8 $ sudo -s sudo: pam_open_session: Bad item passed to pam_*_item() sudo: policy plugin failed session initialization [test case] $ cp /etc/default/locale /tmp/locale $ update-locale --locale-file /tmp/locale LANGUAGE = en_US.UTF-8 + "diff -u /etc/default/locale /tmp/locale" should be empty. - "diff -u /etc/default/locale /tmp/locale" should be empty. + $ update-locale --locale-file /tmp/locale LANGUAGE=en_US.UTF-8 + + The LANGUAGE=en_US.UTF-8 line should have been replaced by + LANGUAGE=en_GB.UTF-8. + + $ update-locale --locale-file /tmp/locale LANGUAGE + + The LANGUAGE setting is now commented out. + + [regression potential] + Apart from the general concerns about a glibc rebuild, this is a simple change to a simple script. Performing the test as in the test case section is enough to ensure it still works. [original description] By passing wrong input as following: sudo update-locale LANGUAGE = en_US.UTF-8 result is: ... #LANGUAGE=en = This "equal" sign that was added makes system completely unusable(can't run sudo anymore): bentzy@bentzy-nb:~$ sudo vim /etc/default/locale sudo: pam_open_session: Bad item passed to pam_*_item() sudo: policy plugin failed session initialization Fixed it booting from installation disk and fixing corrupted /etc/default/locale ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: locales 2.31-0ubuntu9 Uname: Linux 5.5.4-050504-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.6 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: KDE Date: Tue Aug 25 09:36:03 2020 InstallationDate: Installed on 2020-08-17 (7 days ago) InstallationMedia: Kubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) PackageArchitecture: all SourcePackage: glibc UpgradeStatus: No upgrade log present (probably fresh install)
