How to install Zorba in Ubuntu 12.04? When adding repository {using this command: sudo add-apt-repository ppa:juan457/zorba} , getting error "Err http://ppa.launchpad.net precise/main Sources 404 Not Found". can u suggest me how to clear this issue.
The most recent Zorba release (2.2) came out before Ubuntu 12.04 Precise Pangolin, so we didn't build packages for that Ubuntu version.
The next Zorba release (2.5) will be out within the next couple of days, so we will be updating the PPA binaries, including for Ubuntu 12.04.
You may be able to use the Ubuntu 11.10 Oneiric Ocelot packages in Ubuntu 12.04 by adding the following line to /etc/apt/sources.list:
deb http://ppa.launchpad.net/juan457/zorba/ubuntu oneiric main
and then doing "sudo apt-get update; sudo apt-get install zorba". However I can't swear that will work; it's possible some dependent libraries will be different between the two Ubuntu releases.
