I am looking for help installing certbot from Let's Encrypt
NB This worked ~ 1 year ago (on a different server)
I am not a Linux admin and unfamiliar with most of these packages managers (so many!)
Retrospectively following instructions here : https://certbot.eff.org/instructions?ws=other&os=ubuntufocal&tab=standard
( but used dnf not yum )
sudo dnf install -y jdk-24-headful ( not sure required for either ORDS or certbot )
sudo dnf install -y oracle-epel-release-el8
sudo dnf info snapd
sudo dnf install -y snapd
sudo systemctl enable --now snapd.socket
sudo systemctl start snapd
sudo ln -s /var/lib/snapd/snap /snap
so I have snapd up and running
and here : https://certbot.eff.org/instructions?ws=other&os=ubuntufocal&tab=standard
sudo snap install --classic certbot
error: cannot communicate with server: timeout exceeded while waiting for response
I am slightly concerned that the snapcraft.io website looks stale ( I have never heard of them ) so are there newer/better ways ?
OS Details (if relevant)
$ cat /etc/system-release
Oracle Linux Server release 8.10
$ cat /etc/redhat-release
Red Hat Enterprise Linux release 8.10 (Ootpa)
$ uname -a
Linux apex23c-ords-23924 5.15.0-307.178.5.el8uek.x86_64 #2 SMP Wed Mar 19 13:00:52 PDT 2025 x86_64 x86_64 x86_64 GNU/Linux
I normally follow Tim Hall's article - hence used dnf not yum. But even that is ~ 4 years old.

Entirely possible this is an OCI issue - but would not know where to look …
Or could this be firewall on host issue … ?
