<br>
Thanks for reporting this problem.<br>
<br>
Could you please post the output of the following commands, in the system being<br>
upgraded?<br>
<br>
cat /proc/cmdline<br>
cat /etc/sipwise_ngcp_version<br>
debconf-show grub-pc<br>
<br>
<br>
In the meantime, if you want to proceed with the upgrade while we address the<br>
problem, and assumming that the system has been running and booting fine so far<br>
from previous installations and upgrades, and that as a last resort you have<br>
means to restore it if something goes wrong (e.g. boot via another partition), a<br>
workaround to this problem is to edit this file:<br>
<br>
/usr/share/ngcp-upgrade/steps/mr7.5/fix_grub_upgrade<br>
<br>
and add a new line with "exit 0", after the first line of "#!/bin/bash", and<br>
then execute "ngcp-upgrade" again with the same options (target version and so<br>
on), to continue the upgrade at the point where it broke.<br>
<br>
In this way this step will simply not run, and will leave the boot process the<br>
same that it is (without attempting to reinstall it), so it should not break<br>
anything, while assuming that it will continue to boot fine with the current<br>
state. And, meanwhile, this allows you to continue with the other steps of the<br>
upgrade.<br>
<br>
<br>
Hope that helps, and please report back with the info requested so we can try to<br>
improve the step to allow for your system configurations.<br>
<br>
<br>
Cheers.<br>
