During local installation, using a local DVD drive, the following error message occurs during the
mount step of the DVD:
Mount: block device /dev/cdrom is write-protected, mounting read-only
Mount: No medium found
Action
To check for a DVD drive:
# dmesg | grep –i dvd

To check for a CD drive:
# dmesg | grep –i cd

 Exchange the CD drive with a DVD-drive.
 Use a USB stick instead of a DVD.

checks the fingerprints that are stored in the file /.ssh/known_hosts on the Installation Server.
To delete the old entry, search for the host name and IP address in the known_host file. If the
content is encrypted check the line given in the message below.
“Offending key in /.ssh/known_hosts:3”
# scp id_rsa.pub [e-mail]:.ssh/
