>From my several brief tests, this does not appear to be a (recent) regression.
I do see in the apt-key manpage that apt-key is deprecated as of Focal and will be removed after Debian 11 / Ubuntu J/22.04. In the meantime, the `cp some-repo-key.gpg /etc/apt/trusted.gpg.d` method has been brought to the customer as a "workaround" / the new correct method. The signed-by option is a good idea, too! Thank you for your response letting us know that a change to apt-key will be skipped. -- 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/1931178 Title: apt-key fails when POSIXLY_CORRECT environmental variable is set Status in apt package in Ubuntu: New Bug description: apt-key fails when the POSIXLY_CORRECT environmental variable is set. This is due to chmod acting differently with POSIXLY_CORRECT set: chmod tries to use `--` as a parameter with this variable. This prevents some third-party utilities, like pmrun, from using apt- key. --- chmod with POSIXLY_CORRECT unset succeeds with the following commands: ``` touch testfile chmod 0644 -- testfile echo $? ``` The final command prints "0". (This is what the apt-key script expects to happen.) --- chmod with POSIXLY_CORRECT set fails with the following commands: ``` export POSIXLY_CORRECT= touch testfile chmod 0644 -- testfile echo $? ``` The final two commands print these two lines, respectively: """ chmod: cannot access '--': No such file or directory 1 """ (This is unexpected for the apt-key script.) --- As such, when a third party utility that sets the POSIXLY_CORRECT environmental variable, like pmrun, tries to run apt-key, it will fail. Example use similar to what the reporting customer tried: `cat some-repo-key.gpg | pmrun apt-key add -` The chmod examples are run on an up-to-date Bionic container, /usr/bin/apt-key has `chmod #### -- path` commands at line 338 and line 499: GNU coreutils package version 8.28-1ubuntu1 apt package version 1.6.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1931178/+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
