[Bug 602945] Re: apt-cdrom fails due to inconsistent choice of mount points

[Jim Shank]

I am a newbie to Linux...very new! If the following question belongs on
another forum, I apologize. I am having problems trying to burn an .iso
of "Ultimate Boot CD".

A Google search sent me to this forum as a result of the above post from
User: "bim (mng-kingston)" dated 2010-11-24. Bim says:

"The disk utility for /dev/sr0 says
Location: Port 1 of PATA Host Adapter
Capacity: 2.0 KB
Connection: SCSI
SMART Status: Not Supported"

I have a dual-boot laptop (Windows 7 and Ubuntu 11.04). I have had
problems before with Windows not recognizing the cd. It is happening
again today, so I thought I would try it in Linux. When I ran Disk
Utility, I got the exact same information listed by Bim, including the
disk's capacity as 2 KB. Is this a standard response? The capacity of a
cd is about 700 MB.

Nevertheless, I decided to go ahead and try to burn the .iso using
Brasero. After doing so, I told Brasero to check the disk integrity and
it found no problem. What is my next step?

Title:
  apt-cdrom fails due to inconsistent choice of mount points

Status in “apt” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: apt

  I did a network (medialess) install of Ubuintu 10.04LTS on a new PC,
  then added a CDROM source using "apt-cdrom add".

  It recongized my media and added appropriate lines to sources.list
  anmd so on, but installing packages from the CDROM at the console
  command line fails with "file not found" messages.

  On this system (presumably, because it's a medialess install) there is
  no entry for the cdrom in /etc/fstab.

  It looks like what happens is that apt-get, etc., mount the CDROM at
  /media/apt, but when lookng for packages it's searching under /cdrom,
  whgich does not exist.

  Creating a symbolic link to /media/apt at /cdrom allows things to
  work, but should not be necessary.  Apt-cdrom should use the same
  mountpoint for accessing files on the CDROM as it used to mount the
  medium.
