Hi Brad,

Looks like this is because python3.6 is the default on RHEL8 but ceph
depends on 3.8:

pdonnell@vossi04 ~/ceph$ find /usr/ -name \*prettytable\*
/usr/lib/python3.6/site-packages/prettytable-0.7.2-py3.6.egg-info
/usr/lib/python3.6/site-packages/__pycache__/prettytable.cpython-36.pyc
/usr/lib/python3.6/site-packages/__pycache__/prettytable.cpython-36.opt-1.pyc
/usr/lib/python3.6/site-packages/prettytable.py
find: ‘/usr/share/polkit-1/rules.d’: Permission denied
/usr/share/licenses/python3-prettytable
/usr/share/doc/python3-prettytable
find: ‘/usr/share/selinux/targeted/default/active’: Permission denied
find: ‘/usr/libexec/initscripts/legacy-actions/auditd’: Permission denied

pdonnell@vossi04 ~/ceph$ head build/bin/ceph
#!/usr/bin/python3.8

This RHEL has py3.6 and py3.8 installed. But, the prettytable
installed by install-deps.sh is in the python3.6 site-packages. I
wonder how we normally get around this?
