Kubuntu 9.04 & Guest additions

[kestrel1]

I have installed Kubuntu 9.04 as a guest with both a Windows host & a Linux host. The installation goes fine, but when I mount the ISO so that I can install the VBox guest additions I hit a problem. The CD is mounted correctly, but I am unable to see any files on the disc. I get the same result if I use the 'cd' command to get to the /media/cdrom directory & then use the 'ls' command to list the files. I see nothing. If I type 'sudo sh VBoxLinuxAdditions-x86.run' I get a file not found error or something similar. I have used the latest version of VirtualBox (2.2.2) & the slightly older (2.2.0) but get the same result with both. Ubuntu 9.04 & Kubuntu 8.10 both work correctly as virtual machines & I am able to see & install the guest additions in both & have not noticed any problem with other OS's, be them Linux or Microsoft. If this could be looked at I would appreciate it.

How do you mount the CD, and have you tried mounting it from the command line?

Just done a bit more testing. The way I normally mount the CD rom drive or ISO file is to set it up in the CD Rom options before I start the VM. This normally works OK, but not with Kubuntu 9.04. So I started the VM without the ISO set to auto mount & chose to mount it via the Devices menu option -. Install Guest Additions. On doing this I get a message pop up to inform me what has just been plugged in. If I click on the Guest additions image in this pop up box the CD opens in Dolphin & everything appears as it should & I can see all files. I can then 'cd' to the '/media/cdrom' directory & 'ls' & am able to see the files correctly & install the guest additions. However, I also did the same type of mount after rebooting & instead of clicking on the guest additions image in the pop up box, I went straight to the command line & tried to 'cd' to the directory as I had previously. I get no listing after typing 'ls' I then went to display the CD via Dolphin & I get a blank screen again. The only way to get this working appears to be to click on the guest additions image in the pop up box & letting it open in dolphin first. I tried just opening it straight in Dolphin after mounting the image, but I get no files displayed. This is on the Ubuntu 9.04 Host. I will try it on the Windows host tomorrow, but I suspect I will get the same result. At least I have now managed to install the guest additions, but I can continue testing if you require me to, as it may help others. Thanks

This bug report is invalid. There is nothing wrong with VB. It's the OS that doesn't trigger the mount command itself when a CD is inserted. The user has to manually mount the CD. When double clicking on the CD icon on the desktop, the mount command is triggered and the files will be visible. Clearly a bug in the Window Manager of the OS or misconfiguration, not VB. For this reason I made the howto (​http://forums.virtualbox.org/viewtopic.php?f=3&t=15679) terminal based and clearly state that the auto-mount isn't always triggered.

OK, point taken & thanks for the link. Case closed.
