Bug #20355
Updated by François ARMAND almost 3 years ago
I tried to update Rudder from latest 6.2 to 7.0.0.rc1 on CentOS 8.5, but webapp is failing to start.
There was err during install:
<pre><code class="shell">
Running scriptlet: rudder-webapp-1398866025:7.0.0.rc1-1.EL.8.x86_64 1/2
**************************************************************************************
ERROR: rudder-webapp postinstall script failed !
Trying to recover the problem, you should check that your instance is properly working
You should also try to manually execute: /opt/rudder/bin/rudder-upgrade
Such errors should not happen, please open an issue for this problem on
https://issues.rudder.io/projects/rudder/issues/new

Webapp log has been attached.
UPDATE:
The problem is that there was stalled git lock before the update, and Rudder need to check for that, see https://issues.rudder.io/issues/20355#note-3
