Pleare remove
https://aur.archlinux.org/packages/cov-analysis-bin/
from the AUR.
I created the package and was the last maintainer.
However, upstream removed any possibility to download even the binary of
the tool without logging in.
So there is no sense to include it in the AUR anymore.
Note that https://aur.archlinux.org/packages/coverity-submit/
is still available since that tool is open source.
That tool only makes sense when one also installs cov-analysis from some
other source (manually, without AUR), though.
