I can't really blame you for ranting, it is just that rants are a bit harder to follow. I have no idea where, if at all, you are stuck.
To explain the previous (I intended to post an explanation after you confirmed my suspicion): There are several shell scripting languages in linux. Every shell script, on its very first line, has to specify which shell is needed to run the script. The first line of your script will read:
indicating that shell /bin/sh should be used to execute the script.
Traditionally, "bash" and "sh" are different shells (languages), where "bash" is a superset of "sh". On most Linuxes, however, the actual interpreter for both is the same: 'bash'. Hence, many scripts exist on Linux, that declare that they want to be executed using "/bin/sh", while in fact they use the "bash" language. The install script you currently have apparently is one of them.
Ubuntu breaks this tradition of "bash" and "sh" secretly using the same interpreter. Hence, scripts that suffer the problem, above, will break on ubuntu with very vague errors, as you have noticed. There are several ways of restoring the "bash==sh" tradition, which might be a good idea if you are new to all of this, I'm just not sure which one to recommend. Also, I'm not sure you should be installing packages this way in the first place. More about that later :-)
To finish up this subject, the line "bash install.sh" tells linux to use the "bash" interpreter to execute the script, regardless of what the script itself specifies. Hence it functions as the script-writer intended.
On to the next subject:
If you have mounted something, but cannot locate it, start a shell, and type
This will show you everything that is currently mounted and where, although maybe in a somewhat cryptic format.
As a side note:
Ubuntu makes heavy use of "sudo", while "kdesu" sounds kde-specific. I did not study mount-iso in detail, but when given the choice between "sudo" and anything else, your safest bet is "sudo", at least on ubuntu :-)
Last topic:
Being relative new to Linux, I think you are much happier installing software using the package manager. There is an enormous amount of software available (though admittedly not everything) within the ubuntu environment, just a few clicks away from being installed and actually working ;-)
As a first (and one-time) step, click "system->administration->software sources". On the "Ubuntu 6.10" tab (assuming that's what you have), be sure to enable "universe", "main" and "multiverse" (unless you choose not to use "multiverse" for ethical reasons). Click close. That should vastly expand the number of packages you can install.
Next, click "system->administration->synaptic package manager" to launch the package manager. Play around with the "search" function, see if you can locate any software you need. For mounting isos, I think maybe "gisomount" is a good choice. I have not actually tried it myself, but it sounds like it has a graphical UI, and since you can install it from the package manager, installation should be a breeze. It is in the "universe" repository you enabled earlier, which may be why you missed it before.
Please let us know how it goes ;-)
Groetjes,
