# After the process has run through well and there have been packages updated, we recommend to reboot the system afterwards unless you have PXE-clients depending on the machine
'''Note''': === Recovery from a failed update === If your system gets totally broken and does not boot any moreand potentially stops a weird textual screen, reboot recover using these steps: # Reboot the VM holding the Shift key on boot. This will enter the boot loader. # Select "Advanced options". When asked for username and password, use "admin" and your password. # The system will then show a list of Linux kernels available. The newest is most likely the one that is broken, so '''select an older one. ''' At this point do net yet use recovery mode, simply select an older kernel without the "recovery mode tag". # If the system boots into this kernel, be sure to execute #* <code>dpkg --configure -a</code> and #*<code>apt-get install -f</code> as described above and reboot only in the section about shell-based updating# Reboot after both these ran through without errors. Repeat if necessary. Run <code>apt-get update</code> if the system complains about something not to be found. If you can not get any kernel to boot, you need to use a backup.
