I have a fresh installed R31 and updated whonix like described in
https://www.qubes-os.org/doc/whonix/update/
But it finished with:
Whonix firewall script failed:
##################################################
Whonix firewall script failed!
##################################################
iptables v1.4.21: can't initialize iptables table `filter': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.
dpkg: error processing package qubes-whonix (--unpack):
subprocess installed post-installation script returned error exit status 3
Errors were encountered while processing:
qubes-whonix
E: Sub-process /usr/bin/dpkg returned an error code (1)
user@host:~$
How can I fix it?
Kind Regards
