That is a minor bug in update-alternatives, it displays this warning
before taking any action, there is already a FIXME comment in the
source[1]. The alternative is actually removed properly.
Maybe there is a way for procps to avoid the bogus warning, but I do not
currently see a good one.
Cheers,
Sven

The alternative could have been removed in the new preinst before /usr/bin/w is removed by dpkg during the upgrade process. https://www.debian.org/doc/debian-policy/ap-flowcharts.html -- bye, pabs https://wiki.debian.org/PaulWise
