First of all, generally it's not really a good idea to mix apt-get
upgrades with OTA upgrades. The whole philosophy of OTA updates is that
the core-components of the system are read-only and only updated by
system-image during OTA. If you modify packages as in a normal Ubuntu
system, well, there's no guarantee things will work after upgrading.

As for channels. The vivid-proposed channel is no longer supported and
should not be used. We dropped all series-specific channels some time
ago. Currently it's a redirect to the ubuntu-touch/devel-proposed/ubuntu
channel which is building out of wily images. The images there are very
risky.

We have documentation regarding what channels are available and what's
their purpose:

First: as already mentioned, if you want to use OTA updates then don't
enable any custom repositories, OTA's work separately from the standard
apt-get operations. Second: enabling the overlay PPA won't do any good
in a vivid-proposed channel as it's building wily images, while our
stable phones are vivid based.

The recommended channel for the BQ is ubuntu-touch/stable/bq-aquaris.en.
It's good to remember that a channel has nothing to do with a repository
or series, those two are separate beings.

OTA-4 is released to the ubuntu-touch/stable/* channels. Those images,
as already mentioned, are built from the vivid archive + the overlay
PPA. We have a channel that's auto-building daily images from what's
landing to those archives, it's the ubuntu-touch/rc-proposed/bq-aquaris.en.

We dropped the idea of per-series channels as Ubuntu Touch follows a
different release model - more similar to a rolling release. It's best
to reflash your image to the channel that you think is best suiting your
needs. We generally recommend the stable channels, as all the -proposed
ones can be broken without any notice.
