apt list --upgradable shows no additional updates

[David Britton]

Running `apt list --upgradable` does not show any additional packages to install. Should it?

I tried to reproduce and also found that unattached I got no output, but once I was attached I got the full list of packages.

For the record, this output is from update-notifier not the client.

Steps to reproduce
---
1. Trusty system like a lxd or multipass
2. Install ubuntu-advantage-tools from proposed
3. apt upgrade
4. apt list --upgradable

What is the expected behavior? Marking this incomplete.

I saw something similar a while back, and had a conversation with juliank about it:
out 09 11:22:08 <andreas> juliank: but apt list --upgradable is showing:
out 09 11:22:12 <andreas> apport/trusty-updates,trusty-security,now 2.14.1-0ubuntu3.29 all [installed,upgradable to: 2.14.1-0ubuntu3.29]
out 09 11:22:19 <andreas> i.e. upgradable to the same version
(...)
out 09 11:36:04 <juliank> andreas: this is a display bug in apt list, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=753297
out 09 11:36:33 <juliank> Caused by weird behavior in the old pinning implementation, the fix for that is more like a workaround
out 09 11:40:20 <juliank> trusty's pinning implementation is not very good
out 09 11:41:17 <juliank> * apt-pkg/cachefile.cc:
out 09 11:41:20 <juliank> - ensure we have a Policy in CacheFile.BuildDepCache()
out 09 11:41:25 <juliank> maybe that's all that's needed really
out 09 11:49:19 <juliank> andreas: so we could fix that in ESM I guess, it's inserting two lines in cachefile.cc: https://paste.ubuntu.com/p/5FsRtcySx8/
out 09 11:50:23 <juliank> the problem was that pkgDepCache was called with Policy == NULL because Policy was never initialized
out 09 11:50:36 <juliank> other releases are not affected
out 09 11:52:03 <juliank> this caused a mismatch, because depcache never saw the policy and calculated that apport is upgradable to esm
out 09 11:52:17 <juliank> but then we print the candidate version based on policy, and it's the same one :D
out 09 12:00:21 * fginther has quit (Ping timeout: 121 seconds)
out 09 12:06:18 * fginther ([e-mail]) has joined
out 09 12:07:26 <juliank> andreas: Created https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1847496 but I'm not sure about the procedure here

[Andreas Hasenack (ahasenack)]

Have you used apt 1.0.1ubuntu2.24 ? It should have the fix for the bug that was filed during the conversation above, which I'm assuming is the same as this one.

[Joshua Powers (powersj)]

Hmm I was able to reproduce even having 1.0.1ubuntu2.24; adding apt as a affects as well.

[Joshua Powers (powersj)]

This is how I am reproducing:

multipass launch trusty --name t1
multipass exec t1 bash
echo "deb http://archive.ubuntu.com/ubuntu trusty-proposed main" | tee -a /etc/apt/sources.list
sudo apt update -qq
sudo apt upgrade -y
sudo apt list --upgradable

[David Britton (dpb)]

@andreas: Yes, I'm using:

ii apt 1.0.1ubuntu2.24 amd64 commandline package manager

[Julian Andres Klode (juliank)]

Well yes, ESM packages are not included in upgradable if ESM is disabled. It only shows packages that would/should be upgraded if you run dist-upgrade.

[Joshua Powers (powersj)]

Will fix in a follow-up upload with a fix to:

https://git.launchpad.net/ubuntu/+source/ubuntu-advantage-tools/tree/apt-hook/hook.cc?h=ubuntu/trusty-proposed#n218

[Grant Orndorff (orndorffgrant)]

This no longer affects the latest version of ubuntu-advantage-tools so I'm marking Invalid. Please re-open if you think this still applies.
