Which ubuntu 16 are you using? I use the server edition 16.04.2 LTS and there it's just

apt-get install libpng12-dev

...arghh this could be the problem, I can slightly remember a problem with 16.10 and the new Debian release and libpng12...

Do you stick to 16.10 ? - I always recommend to use the ubuntu LTS (long term support) server versions, because you don't have to switch the version every year 🙂

I don't have a 16.10 at hand, what's the error if you open a command line (terminal) and try

sudo apt-get install libpng12-dev

hi Martin, ther u go:

sudo apt-get install libpng12-dev

ok, then you have to adapt your sources.list and use apt-get install afterwards if you really need libpng12-dev

I think this is the answer to your question: dependencies - E: Package 'libpng12-0' has no installation candidate [ubuntu 16.10 Gnome] - Ask Ubuntu

have you tried libpng-dev ? Maybe that's sufficient...

Seems that mirror.kernel.org you used isn't reachable (see the 401 error). Just use an actual valid mirror in your sources list entry or the one you used before za.archive.ubuntu...

Actually, im thinking to change the ubuntu version, cause i have tried others already but still, but thanks for ur time and any news concerned to, plz let me know

Re: need to install libpng12 as Ephesoft dependency

I tried apt-get install libpng12-0 and libpng12-dev on ubuntu 16.04.2 LTS without errors.

16.04.2 LTS is the actual server version with long term support and you should use it for production servers. The next LTS will come in 2018 (maybe 18.04 )

Libreoffice needs some libraries - have a look at GitHub - loftuxab/alfresco-ubuntu-install: Alfresco script based install for Ubuntu maybe you peek a little bit or use it for the install...

hope it helps

could you describe in detail what you tried? Are you installing libreoffice with the alfresco installer, apt-get or another way?

Hi Martin, im trying to install ephesoft to integrate to alfresco, libreoffice is installed automatically as it is ephesoft´s dependency, when the installation starts, occurs that problem mentioned above

Re: need to install libpng12 as Ephesoft dependency

mehe — Tue, 20 Jun 2017 13:32:12 GMT

..ah, I thought it's the alfresco dependency. Maybe you should ask the ephesoft people then...
