Problem with Applicable view for Ubuntu (deb reposiory)
Foreman and Proxy versions:
3.1.2
Foreman and Proxy plugin versions:
3.1.2
Distribution and version:
3.1.2 (Foreman)/4.3 (Katello)

I have problem with view Applicable deb packages for Ubuntu and Debian.
I have 2 serwers katello with the same version 3.1.2 (Foreman)/4.3 (Katello) and OS (Cetntos 7).

On the test serwer Applicable deb packages view correct for Ubuntu. Links for url have got “debs” part.

On the second serwer links is incorrect, but if I enter to section Applicable packages there are.
