Samba is not installable.
Is the install process just causing a immediate reboot and afterwards SAMBA is not installed or runnig?
If so - try.....
When i had this on an older VIX image it was important that the correct sequence was adopted. It would NOT install if settings/plugins had been restored first after a new flash.
Back up your settings (menu -> setup -> vix -> backup manager -> press green for new backup)
Reflash the image to your box (menu -> setup -> vix -> image manager -> press yellow to get the latest version and once downloaded highlight and press blue to flash.)
On reboot set-up video and basic network connection - leave everything else alone (no restore of anything, no scan for channels - nothing else)
Go to the Samba set-up screen and you should get the message:
"Your xxxxx will be restarted after the installation of the service
Are you ready to install packagegroup-base-smbf-server?" with the option Yes and no.
This time when pressing yes a "please wait" message should appear for 5 seconds before the reboot rather than an immediate reboot.
After the reboot hopefully Samba will be installed and you can select start SAMBA
Restore plugins/settings from back-up you've just made and reboot (menu -> setup -> vix -> backup manager -> highlight the dated backup and press yellow to restore)
