I checked my ec2 system version:
cat /etc/system-release
Amazon Linux release 2 (Karoo)
cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
The new version of certbot seems to require snapd to install, but Amazon Linux release 2 does not seem to support the installation of snapd.
sudo yum install snapd
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd

No package snapd available.
Error: Nothing to do
I did not see the relevant system version in the installation teaching of snapd:
I don’t know if Amazon Linux release 2 should be classified in CentOS?
Amazon Linux release 2 is not included in the options, nor did I see the related words.
Epel-release and dnf are mentioned in the CentOS teaching, but they don’t seem to support installation.
Or ec2 just used other methods to install certbot?
