Missing dependency in Ubuntu 18.04 'pdftk'

[schlos]

"E: Package 'pdftk' has no installation candidate"

In Ubuntu Bionic we're missing package which is part of install script (#4971).

The pdftk package in Ubuntu (and its upstream Debian package) was dropped due to its dependency on the now deprecated GCJ runtime.

@schlos how did you resolve this for http://imamopravoznati.org? Did you end up installing from the Cosmic repo as per https://askubuntu.com/a/1028983?

Quite important as it breaks installation on Windows Linux subsystem

Hi @Utopiah - you've commented on a closed ticket as (we thought) we'd fixed this for the latest release! Are you saying that this is broken in Release 0.33 or were you just agreeing that this was an important issue?

If you're installing manually, you'll need to add Cosmic's package list as a low priority APT source to get 'pdftk' per our install script https://github.com/mysociety/alaveteli/pull/5232/files#diff-d5eb0653888644638720a6b98d9d9f1d
