Bash 脚本无法从列表中下载源包

Question

I have a list of packages installed on my Ubuntu 16.04. I have a bash script which tries to download their sources one by one in the appropriate directories (created). I am getting an error:

Reading package lists...
E: Unable to find a source package for xxxx
~/source
~/sourcexxx

My bash script looks like this:

#!/bin/bash
while read package
do
    #cd /mnt
    mkdir $package
    pushd $package
    apt-get -d -q source $package
    popd
done < ins.txt

I don't want to update any system files. apt-get -d -q source xxx works on its own, but not in the script above. What could be the reason?

A part of my ins.txt:

adduser
adium-theme-ubuntu
adwaita-icon-theme
alacarte
alsa-base
alsa-utils
amd64-microcode
anacron
apg
app-install-data
app-install-data-partner
apparmor
apparmor-easyprof

When I do individually for eg apt-get -d -q source adduser, it works

Using your list, this seems to work fine for me (on Ubuntu 16.04) after removing the dpkg-query -f | part:

#!/bin/bash

while read package
do
    echo "Package $package"
    mkdir -v $package
    pushd $package
    apt-get -d -q source $package
    popd
done < ins.txt

Maybe some packages don't have a source, or your ins.txt file contains invalid packages.

But that question would sure have been better posted on Ask Ubuntu .
