Issue renewing certificate

[_az]

The reason I ask about Raspbian is that I can see https://www.piwheels.org/ referenced in your screenshot, which is what that issue is about.

Normally, Debian Stretch does not use that - it's specific to Raspberry Pi distributions. So I think it is more likely that you are using Raspbian or something similar.

The workaround is this specific comment:

I found my pip config:

root@moon:~# cat /etc/pip.conf

[global]

I deleted the /etc/pip.conf file and certboot managed to work again
