If, you are installing in linux dabian based.

Make sure Certbot is not installed first:

Install Certbot

Run this command on the command line on the machine to install Certbot.

sudo snap install --classic certbot

Prepare the Certbot command

sudo certbot --nginx

Test automatic renewal

The Certbot packages on your system come with a cron job or systemd timer that will renew your certificates automatically before they expire. You will not need to run Certbot again, unless you change your configuration. You can test automatic renewal for your certificates by running this command:

sudo certbot renew --dry-run

If you get no errors... your done! Woot woot!

To renew certs you already have:

Run Auto Cert

sudo certbot --nginx

Test Automatic renewal

sudo certbot renew --dry-run

Step-by-Step Fix for Installing snapd on Linux Mint

Ah — good catch. You need to install snapd but linux wont let you... Let’s fix that step by step 👇

🧰 Step-by-Step Fix for Installing `snapd` on Linux Mint

1. Check your Ubuntu base version

Run this first:

grep UBUNTU_CODENAME /etc/os-release

You’ll likely see something like:

UBUNTU_CODENAME=noble

(Mint 22 "Zara" → Ubuntu 24.04 “Noble Numbat”)

2. Remove Mint’s Snap block

Linux Mint disables Snap by default using a preference file.

Run:

sudo rm -f /etc/apt/preferences.d/nosnap.pref

That file literally tells APT: “don’t install snapd.”

3. Add Ubuntu repositories (if missing)

Make sure your /etc/apt/sources.list (or Mint repo list) includes Ubuntu’s repositories.

Run:

cat /etc/apt/sources.list

If you only see packages.linuxmint.com entries and not any archive.ubuntu.com or security.ubuntu.com lines, you’ll need to add them manually.

For Mint 22 (Ubuntu 24.04 base), add this:

echo "deb http://archive.ubuntu.com/ubuntu noble main universe multiverse restricted" | sudo tee -a /etc/apt/sources.list
echo "deb http://archive.ubuntu.com/ubuntu noble-updates main universe multiverse restricted" | sudo tee -a /etc/apt/sources.list
echo "deb http://security.ubuntu.com/ubuntu noble-security main universe multiverse restricted" | sudo tee -a /etc/apt/sources.list

4. Update your package lists

sudo apt update

Now APT should see the standard Ubuntu repositories.

5. Install Snapd

sudo apt install snapd -y

If all goes well, you’ll see it pulling from the Ubuntu repos.

6. Enable Snap service

sudo systemctl enable --now snapd.socket

Then check it:

snap version

✅ Optional: Reboot (recommended)

sudo reboot

Would you like me to give you a single copy-paste command block that handles all these steps automatically for Mint 22 (Zara)?
