Ответ, похоже, заключается в том, что даже с добавлением --names-only, команда apt-cache search ищет предоставленные пакеты. Из man apt-cache:
search regex...
search performs a full text search on all available package lists
for the POSIX regex pattern given, see regex(7). It searches the
package names and the descriptions for an occurrence of the regular
expression and prints out the package name and the short
description, including virtual package names. If --full is given
then output identical to show is produced for each matched package,
and if --names-only is given then the long description is not
searched, only the package name and provided packages are.
Мы можем увидеть, что именно находит поиск следующим образом:
$ apt-cache search --names-only '^linux-' | grep -v '^linux-' |
while read -r pkg rem; do apt-cache show "$pkg" | grep -H --label="$pkg" '^Provides:'; done
