Abiword died with exit code 127 in a Etherpad Lite installation

I’ve just made a Etherpad Lite installation on Ubuntu server 11.04

Its a very simple install, but if want to import/export files you need to install AbiWord

see:

https://github.com/Pita/etherpad-lite/wiki/How-to-enable-importing-and-exporting-different-file-formats-in-Ubuntu-with-AbiWord

 

However it did not work at my installation, got a:

Abiword died with exit code 127

error. It turns out you also need to install Libpng

 

How to install Libpng on Ubuntu see:
