SUCCESS! I have actually remastered Kubuntu!
As it turns out, I didn't need to install Kubuntu 10.04 Trinity to do this remaster. I have already installed it (and made the modifications I detailed in the previous post on the subject) within VirtualBox. I realized that I could share folders between VirtualBox and my Linux Mint installation, so I followed the instructions on the forums to do so. It worked, as Kubuntu 10.04 Trinity in VirtualBox recognized the selected folder on my Linux Mint installation.
I then needed to move folders like .config, .kde3, and .openoffice.org to the /etc/skel/ folder in Kubuntu. After doing so, I used Remastersys to create the ISO image of my Kubuntu 10.04 Trinity installation and moved it to the shared folder. I was then able to test it in VirtualBox, and it worked! Yay!
I have linked the email subscriptions for this blog to my Google account, which also manages Google Docs. I have thus uploaded a compressed file containing my remastered ISO for free download (both as in beer and as in speech). Please note, however, as you try the ISO (either virtualized or as a live DVD/USB), the ISO itself is 1.1 GB which is quite a bit bigger than a CD, so if you want to install this on a computer without a DVD reader, the computer must have a USB port and allow USB boot (or else this just won't work on such a computer). With regard to testing the ISO, note that there may be a full-screen console window that shows up with a bunch of information ending with the word "boot". Just press "Enter" to continue to the boot menu and select either the first (preferred) or second option. Also note that if one is doing this in a virtual machine, after the boot splash there may be a warning saying "Ubuntu is running in low graphics mode"; just click "OK" and let Ubuntu run in low graphics mode anyway. Right before the login screen comes up, an error message may come up. Just click "OK" to proceed. For some reason, the login screen has the username "pvbox" (which was my VirtualBox username) typed in as default. Please change "pvbox" to "guest" and press "Enter" twice. Note that there is no password to log in. You should now be greeted by a screen very similar to the one in my previous post. The KDE desktop and applications should have the Oxygen treatment, and so should OpenOffice.org. Next, note that there is an option to install this remaster (it's a standard Ubuntu installation), but there is no icon either on the desktop or in the KMenu indicating such a possibility. To install this remaster, open Konqueror (which is pinned to the Kicker panel), click on the home folder, click on the icon to the desktop, and then click on the icon labeled "ubiquity-gtkui.desktop"; this initiates the installer. Finally, note that after shutting down, one must press "Enter" (when instructed on the screen) to complete the shutdown process.
I have uploaded this ISO as a 7z compressed file on Google Docs. In most Linux distributions, File Roller or Ark can open and extract 7z files. If they can't, you most likely need to install the p7zip packages from the repositories. In Microsoft Windows, you can download the 7zip program to view, create, and extract 7z files. The file itself is 967 MB, which is still pretty big (but smaller than the 1024 MB Google Docs upload limit — the ISO image is 1.1 GB, which is too big), so downloading may take a while. I will now post the download link. Have fun testing this, and please let me know of any comments, suggestions, and other thoughts you have about this in the comments section (or by email)! Thank you!
