Further investigation showed that the issue seems to occur only inside LXD containers, not in regular VMs. Sorry, I'm so used to working in containers these days that I didn't even think to check a VM as well.
The error also does not seem to occur when --id is used without an argument: root@ct0:~# echo "foo" | logger --id root@ct0:~# echo "foo" | logger --id="$$" logger: send message failed: Invalid argument The exit status is 0 either way, so my scripts don't terminate because of this error. However, messages not being logged when they should be is still a problem, as is spurious error messages in (frequently running) cron jobs, which then flood my inbox. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/1991436 Title: "invalid argument" error from logger command when passing messages via STDIN Status in util-linux package in Ubuntu: Incomplete Bug description: When invoking the `logger` command on Ubuntu Jammy (bsdutils 2.37.2) with explicit PID and passing messages via STDIN ``` echo "some message" | logger -p local0.info --id="$$" ``` the command produces the following error instead of sending the message to syslog: > logger: send message failed: Invalid argument The error does not appear when the message is passed as an argument: ``` logger -p local0.info --id="$$" "some message" # this works! ``` When using process substitution the error only appears for the first log message: ``` exec > >(logger -p local0.info --id="$$") echo "first message" # throws error, message not logged echo "second message" # no error, message logged correctly ``` The issue does not exist in older versions (e.g. Ubuntu Xenial, bsdutils 2.27.1). Workaround: Omit `--id` and include the PID in a tag. ``` echo "some message" | logger -p local0.info -t "foo[$$]" ``` Expected Behavior ----------------- All messages passed via STDIN should be sent to syslog without throwing an error.
