Description Radek Mynar 2021-08-26 13:01:11 UTC 
Description of problem:
Inappropriate error message "Couldn't connect to the server: undefined method `to_sym' for nil:NilClass" is shown when ping pulp3 fails during upgrade from 6.9.4 to 6.10(SNAP 14.0) due to https://bugzilla.redhat.com/show_bug.cgi?id=1996476

Version-Release number of selected component (if applicable):
6.10.0 SNAP14.0

How reproducible:
always

Steps to Reproduce:
1. Continue upgrade after content-switchover fails (as described in BZ#1996476) (maybe some other procedure that causes pulp3 to return 503?)
2. # satellite-maintain upgrade run --target-version 6.10 --whitelist "repositories-validate,repositories-setup,content-switchover"

Actual results:
Following error message is displayed
--------------------------------------------------------------------------------
Check whether all services are running using the ping call:           [FAIL]
Couldn't connect to the server: undefined method `to_sym' for nil:NilClass
--------------------------------------------------------------------------------

Expected results:
Error message should contain something like name of destination server or some different explanation, not "undefined method..."

Comment 1 Gaurav Talreja 2021-09-03 07:42:33 UTC 
Verified.

Tested on Satellite 6.10.0 Snap 16.0
Version: rubygem-foreman_maintain-0.8.13-2.el7sat.noarch

Setup:
1. Make pulp3 service fail in `hammer ping` with,
# foreman-maintain service stop --only pulpcore-api,pulpcore-content,pulpcore-worker@1,pulpcore-worker@2,pulpcore-worker@3,pulpcore-worker@4

Steps:
1. # foreman-maintain health check

Observation:
No more inappropriate error message like "undefined method `to_sym' for nil:NilClass" is visible when ping pulp3 fails.
--------------------------------------------------------------------------------
Check whether all services are running using the ping call:           [FAIL]
Some components are failing: foreman_tasks, pulp3
--------------------------------------------------------------------------------
