During boot process I receive the following message and boot stops.

firmware: failed to load rtl_nic/rtl8168g-3.fw (-2)

I can't do anything.

    That's almost certainly not the problem, since that should still let you boot (albeit without network). Have you tried booting in recovery mode? – Chiraag May 03 '18 at 17:15
  • I tried recovery mode, then i choose the default mode but the same error is appeared again. Please note that i am relatively new on linux – dimitris tseggenes May 03 '18 at 17:30

  • @dimt172z So do you mean recovery mode works but default mode doesn't? – Chiraag May 03 '18 at 23:33

    Yes, i can only use recovery mode as a terminal. I tried to install via terminal the firmware-realtec but is doesn't work. It seems that i have a network problem. – dimitris tseggenes May 04 '18 at 03:07

The error message indicates that a driver software is missing. More specifically, it seems that a network driver (Realtek driver) is causing the issue.
The strange part is that such errors do not affect the boot process. The operating system should boot and you should get a tty.

Some solutions that I may suggest,

  1. Be sure that you haven't changed anything in your harware (ex. add a new NIC)
  2. Boot from a previous kernel version, if there is any on your grub options
  3. Boot from a previous kernel version, if there is any on your grub options, in safe mode. If the system boots, you may look for errors in /var/log/syslog or using the command dmesg.
  4. Restore your kernel with the process described in the accepted answer of this so question.
  5. Boot from a live cd, make a backup of your files/configurations and install Debian again! If it fails during network setup step, you may have a failed hardware.
