Installation with encrypted LVM fails with errno 5 in Virtualbox

[Alex Dueppen]

Installation went normally until the error message suddenly popped up. This is the 20160115 daily ISO but I am unable to run `lsb_release -rd` since I am stuck in the restricted live session. After resetting the VM and trying the installation again, it worked with no errors.

You have an error decompressing the image, which normally indicates corrupt installation medium. Since you say you rebooted and it worked, you might have some faulty ram. You might want to run a memtest on the system for at least 15 minutes. Since it seems to have been some random corruption rather than a bug, there isn't much we can do unless you can find a way to reproduce it while still being able to verify the md5sum of the iso.
