Thanks for your bug report. I believe you meant ubuntu-base, not ubuntu- core (the snap based one)
How did you test this? This seems to me like you forgot to populate /dev, either statically or by bind mounting the /dev from the host. The tarball only contains an empty /dev, and the permissions have not changed. jak@jak-t480s:~/Downloads$ tar tvzf jammy-base-amd64.tar.gz dev drwxr-xr-x root/root 0 2021-12-28 06:01 dev/ jak@jak-t480s:~/Downloads$ tar tvzf focal-base-amd64.tar.gz dev drwxr-xr-x root/root 0 2021-12-28 05:44 dev/ If APT had succeeded *creating* /dev/null as a regular files, all hell would have broken lose, so I am kind of happy that did not happen. For the record, the reason it fails with EPERM seems to be that it's apt-key that's failing and it's run as the user _apt by apt. ** Summary changed: - ubuntu-core on jammy daily: apt-key has no access to /dev/null + ubuntu-base on jammy daily: apt-key has no access to /dev/null ** Changed in: apt (Ubuntu) Status: New => Incomplete ** Also affects: ubuntu-qa-website Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1955859 Title: ubuntu-base on jammy daily: apt-key has no access to /dev/null Status in Ubuntu QA Website: New Status in apt package in Ubuntu: Invalid Bug description: Ubuntu Jammy Core - Smoke test fails. One of the issues that I believe may be the primary issue is that apt- key has no access to /dev/null. root@Joshua-PC:/# apt-get update Ign:1 http://archive.ubuntu.com/ubuntu jammy-updates InRelease Ign:2 http://security.ubuntu.com/ubuntu jammy-security InRelease Get:3 http://security.ubuntu.com/ubuntu jammy-security Release [89.8 kB] Get:4 http://security.ubuntu.com/ubuntu jammy-security Release.gpg [819 B] 0% [Waiting for headers]/usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied E: gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed Ign:4 http://security.ubuntu.com/ubuntu jammy-security Release.gpg Ign:5 http://archive.ubuntu.com/ubuntu jammy InRelease Get:6 http://archive.ubuntu.com/ubuntu jammy-updates Release [89.8 kB] Get:7 http://archive.ubuntu.com/ubuntu jammy-backports InRelease [90.7 kB] 0% [Working] 13.8 kB/s 0s/usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied E: gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed Err:7 http://archive.ubuntu.com/ubuntu jammy-backports InRelease gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed Get:8 http://archive.ubuntu.com/ubuntu jammy Release [269 kB] Get:9 http://archive.ubuntu.com/ubuntu jammy-updates Release.gpg [819 B] 0% [Working] 13.8 kB/s 6s/usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied E: gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed Ign:9 http://archive.ubuntu.com/ubuntu jammy-updates Release.gpg Get:10 http://archive.ubuntu.com/ubuntu jammy Release.gpg [819 B] 0% [Working] 13.8 kB/s 6s/usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied /usr/bin/apt-key: 95: cannot create /dev/null: Permission denied E: gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed Ign:10 http://archive.ubuntu.com/ubuntu jammy Release.gpg Reading package lists...
