I too thought that it was important to file bug reports when things aren't working.  Open source is always a sort of beta test and one way people with less skills than developers could contribute is identifying problems, providing details, answering questions and testing solutions.
 
No one is "demanding" anything gets fixed - this is open source.  It is important, though, that known problems are identified and confirmed by other people so other users that run into the same problem in the future will know and can act accordingly.
 

Thanks Igor.
 
For Reference:
 
chmod 644 /etc/cron.d/armbian-updates  has stopped the INSECURE MODE problem.
 
For item 1)  above to stop IPv6 see http://www.binarytides.com/disable-ipv6-ubuntu/
 
I used this method:
Method 1 - Disable from sysctl
The first method to disable Ipv6 is to edit kernel level parameters via sysctl interface.
 
The kernel parameters that enable ipv6 are as follows
$ sysctl net.ipv6.conf.all.disable_ipv6
net.ipv6.conf.all.disable_ipv6 = 0
$ sysctl net.ipv6.conf.default.disable_ipv6
net.ipv6.conf.default.disable_ipv6 = 0
$ sysctl net.ipv6.conf.lo.disable_ipv6
net.ipv6.conf.lo.disable_ipv6 = 0
 
Note that the variables control "disabling" of ipv6. So setting them to 1 would disable ipv6
Edit the file - /etc/sysctl.conf
$ sudo nano /etc/sysctl.conf
 
And fill in the following lines at the end of that file
 
# IPv6 disabled
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
 
Save the file and close it. Restart sysctl with
$ sudo sysctl -p
 
Check the output of ifconfig again and there should be no ipv6 address
