Comment 8 for bug 1939932

AWS Bug verified with the following script:

-----------------------------------
import logging
import os

from pycloudlib.ec2.cloud import EC2

api = EC2(
    tag="test-ec2",
    access_key_id=os.getenv("UACLIENT_BEHAVE_AWS_ACCESS_KEY_ID"),
    secret_access_key=os.getenv("UACLIENT_BEHAVE_AWS_SECRET_ACCESS_KEY")
)

image_id = "ami-0193aa0a9df84a08b" # Focal pro image
private_key_path = "ec2-{}.pem".format("test-key")
key_name = "test-key"

if key_name in api.list_keys():
    api.delete_key(key_name)

keypair = api.client.create_key_pair(KeyName=key_name)

with open(private_key_path, "w") as stream:
    stream.write(keypair["KeyMaterial"])

os.chmod(private_key_path, 0o600)

api.use_key(private_key_path, private_key_path, key_name)
vpc = api.get_or_create_vpc(name="test-ec2-pro")
instance = api.launch(image_id, vpc=vpc)

print("--- Creating base instance")
print(instance.execute("lsb_release -a"))
instance.execute("sh -c 'sudo apt-get update > /dev/null'")
instance.execute("sh -c 'sudo apt-get install ubuntu-advantage-tools > /dev/null'")
print(instance.execute("ua version"))
print(instance.execute("sudo ua enable fips --assume-yes"))
print("------------------")

print("--- Updating ua package")
cmd = "sudo sh -c \"echo 'deb http://archive.ubuntu.com/ubuntu/ {}-proposed restricted main multiverse universe' >> /etc/apt/sources.list.d/proposed-repositories.list\""
instance.execute(cmd.format("focal"))
instance.execute("sh -c 'sudo apt-get update > /dev/null'")
instance.execute("sh -c 'sudo apt-get install ubuntu-advantage-tools > /dev/null'")
print(instance.execute("ua version"))
print(instance.execute("sudo ua enable fips --assume-yes"))
print("------------------")
instance.delete()

To run that script, you need the pycloudlib dependency, which can be found here:
https://github.com/canonical/pycloudlib/tree/main/pycloudlib
