This has been a stable pipeline script that has worked for more than a couple of years. It just ftp's up the changes to the place we need them after they are pushed to bitbucket. You can google and find a very close example to it.
I have a hard time believing nobody else would be encountering such an error about the content at security.debian.org, so I'm wondering if the underlying linux that this runs under has an issue that Atlassian needs to address.
