How do I debug the yum plugin

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 6

Issue

Due some errors we need to get some debug output from our yum plugin.

Resolution

Reconfigure the /etc/yum.conf for the time you want to investigate the error.

Set the 'debuglevel' to a value of 10 to get more verbosity.

For example:

[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=10
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1

# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h

# Default.
# installonly_limit = 3

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

The output will be provided on the screen.

Root Cause

The yum plugin has a debugging functionality implemented.

Diagnostic Steps

  • yum update
  • yum repolist
  • Any yum operation in general.
