Zimbra Desktop version 2 is currently in beta, which means it's not finished. It means that if you would like to use it, that's great but please be aware that there may be some problems along the way. The idea of a beta program is that the users assist the developers in making the application perfect, it stands to reason that it wont be perfect while it still says beta on it.
Ok, rant aside, I'll offer clarification on your question. When jmhe said to run the script manually, he's refering to running that inside the command window. by typing "./user-install.pl" from the directory that script resides in. Are you familiar with the command line much?
You are right, a PPA could be made, it could even be added to the Ubuntu repositories, but I dont expect that to happen while its still in beta, look out for it when it hits general release though. |
