But still not able to download it:

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd

No package snapd-2.51-1.amzn2.1 available.
Error: Nothing to do

Can you spot my mistake?
Here is my system information:

(base) [ec2-user@ip-10-0-0-89 ~]$ cat /etc/*release

Thanks for taking so much time to help me!
