This assumes you have already installed snapd.

Some distribution include certbot. Let's use apt-get remove, dnf remove or yum remove to remove certbot if it was include with your distribution.

dnf remove certbot

To include classic certbot, there must be a symbolic link between /var/lib/snapd/snap and /snap.

ln -s /var/lib/snapd/snap /snap

Install classic certbot using snap.

snap install --classic certbot

The snap list command should now include certbot.

~]# snap list
Name     Version    Rev    Tracking       Publisher     Notes

core20   20230622   1974   latest/stable  canonical✓    bas

Create a symbolic link between /snap/bin/certbot and /usr/bin/certbot so that just the "certbot" command can be used.

ln -s /snap/bin/certbot /usr/bin/certbot

The certbot --version command can be used to verify that the certbot command is working.

~]$ certbot --version
certbot 2.6.0
