** Description changed: + [Impact] + + TODO Grant + + [Test Plan] + + Reproduce the bug by trying to attach ua on a vm with an old version of + snap. For example: + + ``` + multipass launch -n test-xenial-old-snap xenial + multipass shell test-xenial-old-snap + # inside the vm now + sudo apt update + sudo apt install snapd=2.0.2 ubuntu-core-launcher=1.0.27 + sudo apt install ubuntu-advantage-tools + sudo ua attach YOUR_UA_TOKEN_HERE + ``` + + You should see the error described in this bug below. + + To see the fix in action: detach, install the new version of ua from our + staging ppa and try again. + + ``` + sudo ua detach + sudo add-apt-repository ppa:ua-client/staging + sudo apt update + sudo apt install ubuntu-advantage-tools + sudo ua attach YOUR_UA_TOKEN_HERE + ``` + + Enabling livepatch will still likely fail, but ua will output a + suggestion to update snapd, which will resolve the issue. + + [Where problems could occur] + + TODO Grant + + [Other Info] + + TODO Grant + + [Original Description] + While trying to reproduce https://bugs.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/+bug/1927029, when running `ua attach <token>` on a xenial ec2 instance, I got the following error: ``` Enabling default service esm-infra Updating package lists UA Infra: ESM enabled Enabling default service livepatch Unexpected error(s) occurred.
