Is `dpkg-reconfigure --all` still available in 16.04?

Question

After upgrading to 16.04, I tried to use that command, but it seems that dpkg-reconfigure (or dpkg --reconfigure) doesn't understand the option --all.

Is it still available? If not, is there an equivalent command?

Answer 1

Not equivalent, but probably what you are looking for if you want to be sure, everything is at least somehow configured:

dpkg --configure -a

Answer 2

You can try this script:

for i in `dpkg -l | grep '^ii' | awk '{print $2}'`; do
    echo $i; sudo dpkg-reconfigure $i;
done

It reconfigures all installed packages.

Answer 3

No, dpkg-reconfigure on 16.04 (but also on 15.10) does not have the option --all any more, although it was present in 14.04 (not sure about 14.10).

You could have verified that yourself by checking the command's manpage:

man dpkg-reconfigure

On a 16.04 (or 15.10) system, this manual page will not list an --all argument, while on 14.04 one is present.

If you don't have those systems at hand, just read the online manpages: 16.04 - 15.10 - 14.04
