Re: [Pharo-dev] How to get Pharo into Ubuntu Software center

by Peter UhnÃ¡k

I don't use Ubuntu, but I do use Debian and I see at least these problems 1) Can the AptUrl ( https://wiki.ubuntu.com/AptUrl ) add a PPA repository? >From the link it seems like it can only enable/refresh them? 2) This works out of the box only for Firefox (so you still need instructions for Chrome, but maybe Ubuntu users don't use chrome :)) 3) You need to specify 32bit architecture I have a feeling that the thrid step must be done by user, but maybe there could be 64bit package that would execute script that would add the package and then it would have 32bit package as dep?

How to get Pharo into Ubuntu Software center

by Torsten Bergmann

Hi, in Ubuntu one can click on a link with apt:// protocol to easily install a piece of software right from a webpage: <a class="apt" href="apt://chromium-browser">Install Now</a> It just opens a link to the Software center with the software preselected. Unfortunately Pharo is not part of the Software center :( Can we improve this situation? What is necessary so that Pharo (or ideally the Pharo launcher) gets directly added to the Software center and we just need a link on the webpage? Just want to understand if it is a technical or time issue. Thanks T.

"StandardFont defaultfont pixelSize" or something like that. (Can't check now). But as Esteban said this is maybe not the best solution since a FT can store something else than a string. -- Cheers Cyril Ferlicot
