-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to adduser in Ubuntu. https://bugs.launchpad.net/bugs/1738673 Title: deluser --backup fails because tar --no-unquote option should be used Status in adduser package in Ubuntu: New Bug description: deluser --backup --remove-home (or --remove-all-files) USER aborts if it encounters certain file names, for example the ubiquitous 'C:\nppdf32Log\debuglog.txt' left in Linux home directories by Firefox. The root cause is that 'tar' helpfully "interprets escape sequences" in its filename arguments, so file names containing a backslash followed by 'n' are changed to contain a newline character, and other similar cases. The tar --no-unquote option prevents this. So 'deluser' should pass --no-unquote to 'tar' when creating the backup archive. I'll attach a demo/regression-test script, but in brief: STEPS TO REPRODUCE: 1. touch '/home/testuser/C:\nppdf32Log\debuglog.txt' 2. deluser --backup --remove-home testuser RESULTS: /bin/tar: /home/.../C\:\nppdf32Log\\debuglog.txt: Cannot stat: No such file or directory (deluser aborts without doing anything except creating an empty archive file) ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: adduser 3.113+nmu3ubuntu5 ProcVersionSignature: Ubuntu 4.13.0-19.22-generic 4.13.13 Uname: Linux 4.13.0-19-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.6 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sun Dec 17 15:20:16 2017 InstallationDate: Installed on 2017-12-13 (4 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171018) PackageArchitecture: all SourcePackage: adduser UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/adduser/+bug/1738673/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
