@martinpitt Hey, I'm trying to download_dir /var/log/journal but this doesn't seem to succeed, do you have any idea why it wouldn't work on packit?

Locally I get:

@jelly : download() and download_dir() are a bit "strange" historically, they download relative destination paths into test/. So either adjust your listdir call accordingly, or set relative_dir='.` or specify an absolute destination dir.

[martinpitt]

@jelly btw, there's no difference -- your local output and the one on testing farm fail on exactly the same issue.

I don't recall seeing this in a while so I'll close this PR.
