There are two hilarious bugs in here:
(1) We call _config->FindB("APT::Cache::AllNames","false"), trying to
set the default to false, but we pass a char* instead, which gets cast
to true (as it's != nullptr). So, pkgnames always runs with --all-names
(2) We accidentally exclude virtual packages, hence why we've not seen
that before by excluding any package that does not have a version, by
checking I.FindPkg("any")->VersionList == 0.
Now the trick here is that the check in (2) fails for source packages,
as I.FindPkg("any") does not find a valid package (it returns a pointer
to the start of the cache), but that generates a != 0 VersionList.
Anyway, I've got the fix.

Title:
bash-completion incorrectly shows source package names for APT
Status in apt package in Ubuntu:
In Progress
Status in bash-completion package in Ubuntu:
Invalid
Bug description:
Steps to reproduce:
1. Have Ubuntu 20.04 LTS installed
2. Open terminal, enter one of the commands below
2a. apt install brisk<Tab>
2b. apt source brisk-menu<Tab>
2c. apt-get install brisk<Tab>
2d. apt-get source brisk-menu<Tab>
2e. apt-cache policy brisk<Tab>
Expected results:
* The bash-completion should not lead to package name as there are no binary
packages named with starting part "brisk" (see
https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=brisk )
Actual results:
* all commands below get completed to the name of source package - in this
example named "brisk-menu"
(see
https://packages.ubuntu.com/search?suite=all§ion=all&arch=any&keywords=brisk&searchon=sourcenames).
This is absolutely unexpected, as user can not really install this package in
binary form.
