mid-2011 macbook air stuck on "updates and other offers"

[Hanzo]

Before running installer make the following:
Open terminal.

Code:

# sudo su -# blkid

Check the name it will give you for your cdrom device. For example "Linux Lite 6.0 - Release amd64"

Code:

# add-crdom add --cdrom /cdrom -r

As a name add name from the step above.

Code:

# df

Check which device is mounted as /cdrom. For example /dev/sdb1

Then run installer.


P.S.
If you'll check

Code:

# ps -ef --forest | less

You'll find, that you're stuck on "apt-get install" step.
And while trying to run it manually, you'll get "please insert  the disk labeled <bla-bla> in the drive /media/cdrom/ and press [Enter]"
It's stuck on step

Code:

# mount /dev/<device from the step above> /media/cdrom

Guys, can't you fix it?
