yum makecache failing, unable to run ppa-transfer. Script shows error:

# ppa-transfer transfer-accounts config.ini
[ERROR] | Failed to check migration tool updates: Failed to execute 'yum makecache' command to update yum metadata which is required to perform migration tools update.
Please fix YUM configuration so the command 'yum makecache' does not fail and re-run migration tool.

The error from migration manager means that "yum makecache" command fails:

# yum makecache [Errno -3] Error performing checksum
Trying other mirror.


What this really means that yum cannot calculate the sha256 checksum correctly.


The fix is simple:

# yum install python-hashlib

which makes the necessary libraries available for yum to calculate the new checksums correctly.
