I met this issue in caddy installation. It requires repo ‘copr’ and get an error in yum importing.
I searched on google and find that most of this issue is caused by missing or broken of urllib3
[root@localhost ~]# yum copr enable @caddy/caddy
Plugin "copr" can't be imported
Loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-manager

No such command: copr. Please use /usr/bin/yum --helpWork:
[root@localhost ~]# ls /usr/lib/yum-plugins/This is to find whether copr repo is installed. If so, here will be the copr.py, copr.pyc and copr.pyo in response.
copr.py fastestmirror.py product-id.py search-disabled-repos.py subscription-manager.py
copr.pyc fastestmirror.pyc product-id.pyc search-disabled-repos.pyc subscription-manager.pyc
copr.pyo fastestmirror.pyo product-id.pyo search-disabled-repos.pyo subscription-manager.pyothen cd to this path, start python and import copr.

[root@localhost yum-plugins]# pip install urllib3
Requirement already satisfied: urllib3 in /usr/local/lib/python3.6/site-packages (1.26.12)We already have urllib3 but this the response is from pip of python3 and yum works with python2. So, the actual command is:
[root@localhost yum-plugins]# pip2 install urllib3Or
[root@localhost yum-plugins]# pip2 install --upgrade urllib3Collecting urllib3
