  [INFO] installing package pcre-8.42-6.el8.i686 needs 111MB on the / filesystem

  [INFO] At least 216MB more space needed on the / filesystem.

• There's enough disk space available on the server.

Cause

Bug on leapp script, for reference: Sometimes the temp FS is still too small

Resolution

1. Connect to the server via SSH

2. Run the following command to set the environment variable LEAPP_OVL_SIZE to a higher value:

   # sudo export LEAPP_OVL_SIZE=10000

3. Run the conversion script once again.
