pro attach does not cope well with squid-deb-proxy ACLs

[Seth Arnold]

Hello, my 18.04 LTS system has squid-deb-proxy configured, and it does not have esm.ubuntu.com configured in the ACLs in /etc/squid-deb-proxy/mirror-dstdomain.acl.d/ yet. This causes an error that's not exactly obvious:

$ sudo pro attach REDACTED
Enabling default service esm-apps
Enabling default service esm-infra
Enabling default service livepatch
Installing canonical-livepatch snap
Canonical livepatch enabled.
Failed to enable default services, check: sudo pro status
$ sudo pro status

Unexpected APT error. See /var/log/ubuntu-advantage.log

The ubuntu-advantage.log does have sufficient details to debug the problem. I'm just curious if there's anything we can do here to give a hint without resorting to the log. (Maybe report if apt is configured to use a proxy? I'm really not sure what I'm expecting.)

Thanks

I filed https://bugs.launchpad.net/ubuntu/+source/squid-deb-proxy/+bug/1991860 for squid-deb-proxy, to ask for esm.ubuntu.com to be allowed by default.

Thanks

We discussed and decided to think about a solution on how to better represent the information about proxies. We'll follow up when we get to it.

Hello, Seth

We have implemented (a couple releases ago, sorry I forgot to update this here) a better Unexpected APT Error message, which includes the details returned by apt when the exception happens - so you immediately see (before looking at logs) a pointer to what happened.

I am closing this bug - feel free to reopen if you have any other issue with this solution.

Awesome, thanks!
