Since i installed certbot on Debian 10, it always shows this error:

root@HypeTime:/home/sinusbot# apt update
Hit:1 http://security.debian.org/debian-security buster/updates InRelease
Hit:2 http://deb.debian.org/debian buster InRelease

  404  Not Found [IP: 2001:67c:1560:8008::15 80]

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Does someone know how to fix this error?

    This isn't a programming question and so StackOverflow is not the correct site for it. You could try http://unix.stackexchange.com. – Nate Eldredge Feb 16 '20 at 15:10

    That said, why are you using an Ubuntu repository on a Debian system? Especially when there is [already a certbot package in the main Debian repository](https://packages.debian.org/buster/certbot), which is what [the official instructions tell you to use](https://certbot.eff.org/lets-encrypt/debianbuster-apache.html). – Nate Eldredge Feb 16 '20 at 15:11

    The "focal" version is nout out yet. Maybe you should revert back to a previous Ubuntu version in the sources.list (change focal to disco in the file pointing to this PPA), while still avoiding using an Ubuntu repo on a Debian system. – Cyril Chaboisseau Apr 01 '20 at 21:35
  • Same issue here. Focal gives the error `module 'acme.challenges' has no attribute 'TLSSNI01'` – vinyll Apr 26 '20 at 07:33

I got rid of the error message on Ubuntu 20.04 by removing the ppa repository. It took me a long time to find out the exact command argument, so this might help others :-). I used the command:

sudo apt-add-repository -r ppa:certbot/certbot

After that, the following commands do not generate any errors:

sudo apt update
sudo apt-get update

    for other ways to remove the ppa repository (including GUI tool Software & Updates) you could check [How to list and remove PPA repository on Ubuntu 20.04 Linux](https://linuxconfig.org/how-to-list-and-remove-ppa-repository-on-ubuntu-20-04-linux) – jimbod119 May 28 '20 at 19:17

    Thank you so much for this. @jimbod119 – Pravas Sep 11 '20 at 17:26

The latest source works just fine and can be installed with a one-liner to install certbot.

curl -o- https://raw.githubusercontent.com/vinyll/certbot-install/master/install.sh | bash

That solved for me, and there's an uninstall also when certbot PPA will be fixed again.

  • while this is still working and makes sense when willing to install the latest version, PPAs now released an upgrade that installs certbot on Focal – vinyll Jun 26 '20 at 21:01

by following Ubuntu 18.04 certbot installation instructions on Ubuntu 20.04.

I should've followed the Ubuntu 20.04 certbot installation instructions, which avoid the command sequence sudo add-apt-repository ppa:certbot/certbot followed by sudo apt install python-certbot-nginx and simply execute

sudo apt install certbot python3-certbot-nginx

Note that the 20.04-friendly command uses python3 in the command, and not just python.

To be fair, I wasn't the only one dealing with this issue. This other post about solutions that offer the -r option to remove repositories helped me figure out in which direction a solution to my issue could be.

See @vinyll's answer for "A one-liner Certbot install is available with the uninstaller included. Works also on Ubuntu 20.04." I did not follow that route because I'm not to keen to uninstall packages without being absolutely certain what they're dependencies for. Since I wasn't 100% certain at the time, it was easier to just follow the installation instructions for the proper OS than uninstall it risking eliminating needed dependencies without being aware.

@vinyll answer helped me that am dealing with Ubuntu server 20.04. There's just a little drawback with it: installs the current head of the repository, which currently is 1.9.0.dev0.

I suggest to look at Certbot repository for the desired release tag - in my case v1.8.0 that refers to the just released version 1.8.0 - and to edit the script to "checkout" it.

The script would become (to install Certbot v1.8.0):

#!/bin/bash

ROOT=~/.certbot-src

# Remove older versions if existing, for a simple re-install/update.
rm -rf $ROOT

# Clone certbot source.
git clone https://github.com/certbot/certbot $ROOT

# Check if python3-venv is installed, and install it otherwise.
CHECK_PACKAGES='python3-venv'
if ! dpkg -s $CHECK_PACKAGES >/dev/null 2>&1; then
  echo "The packages '$CHECK_PACKAGES' are not installed. "
  echo "They will now be installed automatically with 'sudo apt-get install $CHECK_PACKAGES'."
  sudo apt-get install -y $CHECK_PACKAGES
fi

# Checkout the desired release TAG.
cd $ROOT
git checkout v1.8.0 # Replace v1.8.0 with the TAG you chosen

# Setup virtual environment for certbot.
sudo apt-get install -y python3-dev python3-venv gcc libaugeas0 libssl-dev libffi-dev ca-certificates openssl
python3 tools/venv3.py

# Link installed certbot version, so it can used everywhere.
sudo ln -s $ROOT/venv3/bin/certbot /usr/local/bin/

NOTE: if you want to do a clean install and you are going to remove an old Certbot version, do it carefully - e.g. there could be configuration files that would be deleted using apt purge certbot or apt autoremove --purge certbot, bringing the new Certbot installation in an inconsistent state; this answer may help.

I have recently installed certbot using this command:
sudo snap install --classic certbot

    Thanks! I was having issues on a Ubuntu 20.04 server and ran this, which worked in the end. Just a comment, this should be carried out as part of the full certbot installation process - instructions at https://certbot.eff.org/lets-encrypt/ubuntufocal-nginx , otherwise might run into some issues with older certbot packages – Daniel Vieira Jan 10 '21 at 17:53
