I have installed previously Certbot on Ubuntu, but I believe the package wasn't yet available for this distribution yet, so I believe I installed it from a pre-built package (maybe, I'm really not sure). Anyway, right now I have certbot 0.26.1 installed:
certbot --version certbot 0.26.1
I tried to install it using the guide from here: https://certbot.eff.org/lets-encrypt/ubuntubionic-nginx
Here are some outputs from the current system:
apt-get install python-certbot-nginx python-certbot-nginx is already the newest version (0.28.0-1+ubuntu18.04.1+certbot+3). certbot --version certbot 0.26.1 which certbot /usr/bin/certbot dpkg-query -L python-certbot-nginx /. /usr /usr/share /usr/share/doc /usr/share/doc/python-certbot-nginx /usr/share/doc/python-certbot-nginx/changelog.Debian.gz /usr/share/doc/python-certbot-nginx/copyright
so it looks like to me, that "python-certbot-nginx" package doesn't install any binaries. That am I doing wrong here? I have some totally different packages that can be upgraded (e.g. MySQL, PHP), but I can upgrade these only this sunday. But I believe this is absolutely unrelated to my problem. Thanks!
