Comment 4 for bug 1829106

The errors were (in /var/log/syslog):

May 15 03:08:39 juju-manual-jenkaas-java-compatibility-kit-bionic-1 bash[19909]: Exception in thread "main" java.nio.file.AccessDeniedException: /var/lib/jenkins/slaves
May 15 03:11:48 juju-manual-jenkaas-java-compatibility-kit-bionic-1 bash[20160]: Exception in thread "main" java.nio.file.AccessDeniedException: /var/lib/jenkins/slaves/jenkins-slave-1

which is a pretty unhelpful way to report the non-existence of something.

I just realized my original report was somewhat unclear because this was when I also discovered that install -d works like "mkdir -p"; the command above creates any missing directories.
