UCS install failing at 'Installing Additional Software'

installation

#1

I’m installing on a VM from an ISO file, got the file mounted as a cdrom, install’s going smoothly, then promptly hits a wall when it tries to install the software packages. I checked syslog and found this worrisome patch in it:


Aug 30 23:07:47 main-menu[219]: INFO: Menu item 'apt-setup-udeb' selected
Aug 30 23:07:47 apt-setup: Using CD-ROM mount point /media/cdrom/

Aug 30 23:07:47 apt-setup: E: No CD-ROM could be auto-detected or found using the
default mount point.

So apparently it’s unmounting the ISO file for some inexplicable reason, attempting to remount it, failing, and then because the file is unmounted it’s unable to install the packages. Does anyone know of a workaround for this?

Hi!

Never seen this before :confused:
What ISO file did you use? And can you give us the md5sum of that file?

Regards,

I used the file the website had for its download link: http://download.univention.de/download/images/UCS-Installation-amd64.iso and the MD5 is 538ce0652beec98cb77499121b3dec20, matching what you have listed on the site. For reference, I’ve been following the directions here: https://www.linode.com/docs/tools-reference/custom-kernels-distros/install-a-custom-distribution-on-a-linode

I’ve re-downloaded the file, attempted again, same results pointing the cdrom to /dev/sdb (the drive the ISO was dd to):

Good Morning @Valatar,
which virtual machine did you use? Virtual box, KVM, or VMPlayer. What is the Host OS?

Greetings

It’s whatever linode is running their VPS off of, I’m afraid I haven’t been able to find out exactly what that is. I’m going into rescue mode to dd the ISO onto a drive, then rebooting from the ISO to run the install. It’s in full emulation mode; in the default paraemulation mode it couldn’t see the drives and failed right off the bat.

Good day Valatar,
I think a possible way of avoiding this breakdown is to download an already prepared copy of UCS from the website below, for the appropriate VM you are using. you will just have to import the image, rather than install it from fresh.

Bye for now and enjoy the installation.
Greetings
