My Ubuntu 14.04 lts server died so I rebuilt it with 20.04 last night (April's not that far around the corner), and I thought it was finally time to get my Subsonic site behind some encryption. My guess is that certbot just isn't ready for 20.04, as I can't get the ppa installed (404's on focal rele…

For a very fragile workaround, you can edit /usr/lib/python3/dist-packages/certbot_nginx/configurator.py and replace return [challenges.HTTP01, challenges.TLSSNI01] with return [challenges.HTTP01] (or you… can use the webroot plugin)

[image] adenansu: TLSSNI01 this is obsolete. did you move over your config files for certbot from ubuntu 14.04? you need to edit them and move to http-01 or tls-alpn-01 or dns-01

[image] Giuseppe C.: this is obsolete. did you move over your config files for certbot from ubuntu 14.04? you need to edit them and move to http-01 or tls-alpn-01 or dns-01 This is my first time using LetsEncrypt/CertBot. Completely fresh 20.04 install, no settings/configs transferred over.

this doesn’t make any sense, other than a bug in certbot itself. try adding a --preferred-challenges=http switch anyway or maybe use another acme client, like acme.sh

$ sudo certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email (my email) --domain earnom.adenansu.com --preferred-challenges=http Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator nginx, Installer nginx Obtaining a new certificate Performing th…

[image] adenansu: Right, I’m using the official one, I thought I saw somewhere that CertBot 1.0 had been released late last year, so I thought this 0.40 version was old. Oh, you're absolutely right, 0.40 is old.. However, the PPA is even older... For some reason, the certbot team has issues k…

[image] Osiris: What version of the nginx plugin is installed? python3-certbot-nginx version 0.39.0-1

[image] adenansu: File “/usr/lib/python3/dist-packages/certbot_nginx/configurator.py”, line 1110, in get_chall_pref return [challenges.HTTP01, challenges.TLSSNI01] it looks like you have mismatched versions of python3-certbot and python3-certbot-nginx, ubuntu/debian packaging bug.
