Public bug reported:
When installing ubuntustudio 12.04 alternate (alpha) from a usb stick.
(this may affect ubuntuserver as well) There is a spot when I can choose
"work flows" to install. (server allows choosing services to install) If
I choose less than all of the choices and then after install decide I
missed one... I would insert the usb stick I installed from in place of
the cdrom... then I can set apt to search the "cdrom" with the
settings->software sources applet. by Checking cdrom on. I get this
applet from the update manager or synaptic as well. Anyway, both
aptitude and synaptic will show me the meta package I want to install,
but both also tell me to insert the install cdrom... which I don't have
(no drive in fact) and do not see the usbstick. So, I mount the
usbstick... it mounts at /media/G8, I mv cdrom romcd and then ln -s G8
cdrom This makes a link and I can see the right files in /media/cdrom. I
try one of the two install programs again.... they dismount G8 and try
to mount the "cdrom" and I get the same error message. Try two. I
remount G8 my usb stick with the iso image and the link is again valid.
I take a terminal session and cd into a directory on the usb stick and
do an ls to see it is there. This makes the usb stick "busy" and not
able to be unmounted. Now I can install the missing software.
As there are many newer computers with no dvd/cdrom drive, there needs
to be either a mounter that mounts the usb stick as if it was the cdrom
or a second option that looks for a usb stick instead of a cdrom. This
would be the case if I had custom software on a usb stick too... I guess
this is really a bug for choosing software sources. It just seems that
If I use a USB stick instead of a disk for the original install, when I
select "cdrom" to add stuff later it should accept a usb stick then too.
