*** Bug 1643177 has been marked as a duplicate of this bug. ***
This was introduced in 77ed56fb0392f8c5f0fec094ccc422b98f2f62fb which changed the bind host to :: instead of *. If the IPv6 kernel module is disabled then you can't listen on ::. The workaround is to listen on * again by rerunning the installer with:
Note that you must quote the * because the shell will expand it otherwise.
The long term solution is adding a migration and/or check to the installer that does this automatically for the user.
Confirmed on my system that Ewound's workaround in c8 does indeed resolve the issue.
Created redmine issue https://projects.theforeman.org/issues/25460 from this bug
Upstream bug assigned to email@example.com
Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/25460 has been resolved.
Verified fix in 6.4.2 snap 1
1. Disabled IPv6 using the ipv6.disable kernel flag method from https://access.redhat.com/solutions/8709
2. Removed IPv6 entries (including localhost) from /etc/hosts
3. ran "satellite-installer --scenario satellite -v"
The install was successful and foreman-proxy started.
