I've recently installed Blogilo in Elementary OS (which is based on Ubuntu). It installed without any complains, however, when I have fire it up - I was greeted by "Cannot connect to database".
Of course, I have turned to Google for help, and here's what I found:
get a terminal session open:
Ctrl + Alt + T
sudo apt-get install libqt4-sql-sqlite
Start Blogilo and enjoy desktop blogging in Elementary OS or any Gnome session!
