It'll work if /var/lib/dpkg/available is being kept up to date, which
apt doesn't do by default.  You can use "dselect update" in place of
"apt update" to update the available file as well as doing the other
index-update tasks.

dpkg-query --load-avail not working?

2018-05-27 Thread Tong Sun
The man page for `--load-avail` says that it will *"also load the available
file". *
This means it will work for uninstalled packages as well as the installed
ones, right?

The answer from
https://www.linuxquestions.org/questions/linux-newbie-8/dpkg-list-4175503904/
seems to concur with this:

If you want a list of ALL available packages.
> # dpkg-query --load-avail -l '*'


If so, then somehow dpkg-query --load-avail is not working:

$ dpkg-query --load-avail --list 'golang-github-*'
dpkg-query: no packages found matching golang-github-*

Anyone can help/confirm, etc? Thx.
