rhsm.log

Moving to RHEL/subscription-manager as this is seemingly related to that component and not Satellite, but I will do some testing and confirmation.

Confirmed that this is non-specific to Satellite, the same occurs against SAM (I know, not that different.. per say), but as well against the Customer portal / Prod candlepin.

This is simply due to rhsm_icon.json not existing prior to us trying to do something with it. It gets created immediately after, and therefore you do not see the error again.

Its contents appear to always be '1'.

Can we handle this issue differently to steer people away from the "false" error?

*** Bug 1467837 has been marked as a duplicate of this bug. ***

Reproducing the failure on RHEL74 with the following build:
======================================================

# subscription-manager version
server type: Red Hat Subscription Management
subscription management server: 3.4.5.25-Unknown
subscription management rules: 5.26
subscription-manager: 1.19.21-1.el7
python-rhsm: 1.19.9-1.el7

Register system against satellite 6 server and watch the rhsm.log

Make sure rhsm_icon.json doesnt exist

# ll /var/lib/rhsm/cache/rhsm_icon.json 
ls: cannot access /var/lib/rhsm/cache/rhsm_icon.json: No such file or directory

Verification steps on rhel75:
=============================

Install the Satellite6 server's certificate on the system

With new fix ,the following DEBUG message should appear in log file: "Cache file: /var/lib/rhsm/cache/rhsm_icon.json does not exist yet " to view this Debug message set the log level to "Debug" 

ex: default_log_level = DEBUG

Make sure rhsm_icon.json doesn't exist

^^ observed that a DEBUG message is now displayed in rhsm.log stating " rhsm_icon.json doesnt exist" and a new file was written.

Based on the above observations , marking the bug as verified!!

Moving the bug to "New"  based on the following observation :

1) Deploy a fresh RHEL75 machine , OR make sure that "/var/lib/rhsm/cache/rhsm_icon.json" file does not exist 

2) WITHOUT registering the sysstem , execute `service rhsmcertd restart" 

observed following error message on the rhsm.log

2017-11-16 12:39:01,884 [ERROR] rhsmd:13540:MainThread @cache.py:130 - Unable to read cache: /var/lib/rhsm/cache/rhsm_icon.json

^C

Similar to the fix made to this bug , (and as verified in comment 8 ) , request you  to have the same Debug messages displayed in the rhsm.log instead of the traceback error.

Based on the discussion with Jiri , moving this bug to "New"

Make sure the file "/var/lib/rhsm/cache/rhsm_icon.json" file does not exist 
and 

Restart rhsmcertd service ( make sure rhsmd service is running)
