I remembered that I've left a note at the wiki page
See #310

First point release of 14.04 (July 24) has been made, posting here for updates. This and wkhtmltopdf packages are holding back upgrade.

Where will I be able to find this PPA for Ubuntu 14.04 ?

hdave: It's not available yet, a "sub-repo" (whatever it's called) has to be made for 'trusty' on the coolwanglu-pdf2htmlex PPA here:

https://launchpad.net/~coolwanglu/+archive/ubuntu/pdf2htmlex

Using these commands

sudo apt-add-repository ppa:coolwanglu/pdf2htmlex
sudo apt-get update
sudo apt-get install pdf2htmlex

would help me install pdf2htmlex on the following systems??

ubuntu 12.04
ubuntu 12.10
ubuntu 13.04
ubuntu 13.10 ??

I have just started using it on ubuntu and hence the question.

From a glance, yes, I think it's basically all the common ones out besides Trusty (14.04), the new LTS Ubuntu. Think there's one other on top of those 4.

@djvs Did you have any luck with using this?

pdf2htmlex in Ubuntu 14.04, please add the follwing ppa:

https://launchpad.net/~fontforge/+archive/ubuntu/fontforge
https://launchpad.net/~coolwanglu/+archive/ubuntu/pdf2htmlex

Then
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install pdf2htmlex
sudo apt-get -f install

This is still useful

I'd like to try pdf2htmlEX on Debian (9), but it doesn't work:

~# apt-get install pdf2htmlEX
E: Unable to locate package pdf2htmlEX

~#apt-get install software-properties-common

~#apt-add-repository ppa:coolwanglu/pdf2htmlex
=== THIS PPA IS DEPRECATED!! ===

~#apt-add-repository ppa:https://launchpad.net/~fontforge/+archive/ubuntu/fontforge
…
softwareproperties.shortcuts.ShortcutException: Cannot add PPA: 'ppa:~https/ubuntu/ppa'.
ERROR: '~https' user or team does not exist.
Error: 'ppa:https://launchpad.net/~fontforge/+archive/ubuntu/fontforge' invalid

Thank you.
