[Bug 906125] Re: apt can't find "CD" when using a usb stick

[Micah Gersten]

Reassigning to ubiquity as the line that's added to
/etc/apt/sources.list should reflect which medium is used to install.
This might also be a feature request for apt to support a USB stick as a
repository, but I'm not sure.

** Package changed: aptitude (Ubuntu) => ubiquity (Ubuntu)

Title:
  apt can't find "CD" when using a usb stick

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  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.
