Public bug reported: Since PAM 1.4.x, pam_env's behaviour has silently changed and now it fails to parse/doesn't accept /etc/environment files that don't end with a newline.
It's easy to reproduce: $ lxc launch ubuntu-daily:jammy pam-env-test --vm $ lxc shell pam-env-test # # Note that pam-1.4.x is currently in jammy-proposed as I write this bug. # cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list # Enable Ubuntu proposed archive deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe EOF # apt update # apt install libpam-modules libpam-runtime libpam-systemd -y # reboot $ lxc shell pam-env-test # apt policy libpam-modules libpam-modules: Installed: 1.4.0-10ubuntu1 Candidate: 1.4.0-10ubuntu1 Version table: *** 1.4.0-10ubuntu1 500 500 http://archive.ubuntu.com/ubuntu jammy-proposed/main amd64 Packages 100 /var/lib/dpkg/status # echo 'http_proxy=http://invalid.address/' >> /etc/environment # printf 'no_proxy=gnu.org' >> /etc/environment # su - # curl gnu.org curl: (5) Could not resolve proxy: invalid.address The right output should have been similar to: # curl gnu.org <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="http://www.gnu.org/">here</a>.</p> <hr> <address>Apache/2.4.29 Server at gnu.org Port 80</address> </body></html> This bug has impacted autopkgtest.u.c; see the following MP: https://code.launchpad.net/~sergiodj/autopkgtest/+git/development/+merge/412771 ** Affects: pam (Ubuntu) Importance: High Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1953201 Title: pam_env doesn't accept /etc/environment files that don't end with newline anymore (PAM 1.4.x behaviour change/regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pam/+bug/1953201/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
