Comment 7 for bug 1990450

I tested 1:18.04.11.15 on a xubuntu bionic system where I downgraded ntfs3g to be able to see the 'update available' UI from update-manager

There is a cosmectic issue where the '>' sign is displayed over the checkbox but more important, the items associated to the few updates available in the esm-apps repository are displayed as empty lines and selecting one displays those exceptions

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apt/cache.py", line 289, in __getitem__
    return self._weakref[key]
  File "/usr/lib/python3.6/weakref.py", line 137, in __getitem__
    o = self.data[key]()
KeyError: ''

During handling of the above exception, another exception occurred:

    rawpkg = self._cache[key]

apt displays the right information

The following security updates require Ubuntu Pro with 'esm-apps' enabled:
  libopenjp2-7 libzmq5 libopenmpt0 libsoundtouch1 libmysofa0

I'm marking the SRU verification as failed at least on bionic
