Apt-get Failed to fetch on debian jessie

[JoeMurray]

I’m taking over a server and running into some problems that seem to be related to trying to update certbot on debian from an ubuntu repo, but I may be wrong as I’m not an expert on apt.

My /etc/apt/sources.list.d/certbot-certbot-jessie.list contains two lines:
deb http://ppa.launchpad.net/certbot/certbot/ubuntu jessie main
# deb-src http://ppa.launchpad.net/certbot/certbot/ubuntu jessie main

When I run
sudo apt-get update
I get
W: Failed to fetch http://ppa.launchpad.net/certbot/certbot/ubuntu/dists/jessie/main/binary-amd64/Packages 404 Not Found

http://forums.debian.net/viewtopic.php?t=123416 suggests the problem may be because I’m attempting to install an ubuntu package on debian, but that’s what the certbot docs say to do:
https://certbot.eff.org/all-instructions/#debian-8-jessie-apache

What is best way to setup things so I can update certbot properly on debian 8 jessie ?

TIA

Is certbot already installed from the PPA and you’re trying to update it? Or are you trying to install it now?

It’s installed and I’m just trying to update it, or at a minimum configure things in apt so it will update when it needs to be updated.

Certbot 0.10.2 isn’t the version from the Ubuntu PPA; it’s the version from Debian’s jessie-backports repository. If it was installed from jessie-backports, a normal apt-get upgrade will upgrade it to the latest version from there (which is currently 0.10.2, which you already have).

Check https://backports.debian.org/Instructions/ to confirm that you have jessie-backports enabled.

If you need a newer version than the one in jessie-backports, you can uninstall it and install certbot-auto instead (though note that you’ll have to set up your own renewal cron job then).

Since Ubuntu PPAs aren’t designed to work on Debian, I wouldn’t recommend trying to update it from there.
