Let’s Encrypt
I use a droplet to host some, mainly, apache redirects at this point. IT has some SSL certs managed via Lets Encrypt which is awesome. I was using the snapd install of certbot but that stopped working so I had to switch to the python version.
To remove the old one I had to manually delete a directory, then delete a link in the /usr/bin directory before I could successfully follow the install instructions.
It seems to be working. Hopefully I can stop mucking about with this stuff soon.
