[Kolab-devel] Erlang security update breaks guam on Debian 10

[Christoph Erhardt]

Hi Christian,

unfortunately I'm not familiar with the admin side of OBS. The most plausible 
thing I have found would be this settings page:

  https://obs.kolabsys.com/repositories/Debian:10.0

The mirror URLs configured there lead to a 404, though. It seems there's a 
path component (`/dists/`) missing in the middle.

  Broken: https://mirror.switch.ch/ftp/mirror/debian/buster
 Working: https://mirror.switch.ch/ftp/mirror/debian/dists/buster

Maybe this will suffice to trigger a download-on-demand [1] on the next 
package build.

Best,
Christoph
