or "and will now run a desktop...."

I tried installing it with a CD.. it installs ubuntu to a certain point and then stops (after the name password window).. the last thing I see before the error pops up is a big white window with an ">" on the right side.

I tried to gather some debug info via ctrl+alt+f2 but whenever I type something in it tells me I do not have permission to do so.

  • This is not a corrupt media problem - I verified two different burns. It seems to be the slideshow package. The slideshow program comes up on the screen just before the error...

    Why will this work? What about the slideshow causes problems? Jun 12, 2012 at 18:23

    this solution worked for me perfectly with 12.10 on a Sony Vaio. Slideshow was crushing the installation process abruptly. I removed ubiquity-slideshow-ubuntu from terminal during re-installation (thus the slideshow local url could not be found and accessed) and installation continued and exited normally.

  • This solution also worked for me when installing 20.04 inside VirtualBox. I initially thought this issue was a HyperV issue, but after testing with it turned on/off this solved it. Aug 3, 2020 at 6:58
  • another solution is downgrading vm compatibility. For example, downgrade from EXSI 7.0 to workstation 12.

It seems likely that your installation media is corrupted--in my experience, that's the most common cause of this kind of installation error.

You should MD5 test the .iso image you downloaded. If that doesn't check out, then you'll have to download a new .iso and start over.

If it does check out, then you should check the installation media for defects. This applies to both CD/DVD media and to USB flash drives.
