Fail to add APTonCD to Repositories

[Kwok Ho Yin]

Binary package hint: synaptic

I just installed Ubuntu 10.04 LTS and I found that sometimes I could not add my APTonCD in the repositories by Synaptic (0.63.1ubuntu6):

Situation #1:
1. Insert APTonCD to the CDROM
2. Then system will mount the CD automatically and "APTonCD colume detected" dialog box is shown. At this time, you can choose "Cancel" or "Start package manager" for the question "Would you like to open it with package manager?"
3. If I press "Start package manager" button, then I can find my CD in the "Software Source --> Other software" page

Situation #2:
1. Insert APTonCD to the CDROM
2. Then system will mount the CD automatically and "APTonCD colume detected" dialog box is shown. At this time, you can choose "Cancel" or "Start package manager" for the question "Would you like to open it with package manager?"
3. Press "Cancel" button
4. Then start Synaptic Package Manager (System --> Administration --> Synaptic Package Manager)
5. Goto "Other Software" page (Settings --> Repositories --> Other Software)
6. Press "Add CD-ROM" button and system will show "Please insert a disk in the drive" dialog box.
7. Press "OK" button and then the error message "Error scanning the CD E:Failed to mount the cdrom" will be appearred

Situation #3:
1. Insert APTonCD to the CDROM
2. Then system will mount the CD automatically and "APTonCD colume detected" dialog box is shown. At this time, you can choose "Cancel" or "Start package manager" for the question "Would you like to open it with package manager?"
3. Press "Cancel" button
4. Start "Terminal" and type "umount /media/APTonCD" to umount the CD
5. Then start Synaptic Package Manager ourselves (System --> Administration --> Synaptic Package Manager)
6. Goto "Other Software" page (Settings --> Repositories --> Other Software)
7. Press "Add CD-ROM" button and system will show "Please insert a disk in the drive" dialog box.
8. Press "OK" button and then the error message "Error scanning the CD E:Failed to mount the cdrom" will be appearred

This bug is also active in Edubuntu 10.04, both when using Synaptic or Kpackagekit. It is impossible to add the install DVD as a repository source in order to install packages from the DVD.

i just installed the latest download of ubuntu last night and once I inserted CD into my DVD drive scenario 1 did not even occur. No nothing but my upgraded edition on another PC with Lucid did have a popup asking me if I wanted to start package manager. Weird.
