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