Debian Debootstrap Error

Debian Debootstrap error

Debian Debootstrap Error

Debian Debootstrap Error was the message i got while installing Debian 8 on my HP Proliant DL380 G7. Trying several times, and failing with the same message almost every time: Debootstrap Error
Some times saying it was not a Debian Install CD-ROM. One user suggested that UNetbootin should be avoided when using bootable install USB. Or else you would end up with Debian Debootstrap Error. UNetbootin have worked just fine in the past, so I figured it should work fine this time too. However I have also installed Debian 8 in past with out any problems. But never on my “new” server. I almost went to the drastically step and downloaded Ubuntu. Just almost 😉

However another user suggested that the CD-Rom was not mounted. And that could be solved directly from the installer. Here is how you do it.

When the message appears, wither Debian Debootstrap Error or not valid CD-rom.
Hit Alt + F2 and then confirm with .
Type: mount /dev/sdc1 /cdrom
Hit Alt + F1 to return to the installer.

You should now be able to continue you Debian install.
This took me a while to get past, so please enjoy!
