[Pkg-utopia-maintainers] Bug#906193: network-manager: nm ignores IPv6 settings in /etc/NetworkManager/system-connections/Wired\ connection\ 1

[Freek de Kruijf]

Package: network-manager
Version: 1.12.2-2
Severity: normal
Tags: ipv6

Dear Maintainer,


   * What led up to the situation?
   I want to use static addresses for IPv4 and IPv6
   The IPv4 configuration works as expected.
   The IPv6 configuration is completely ignored.
   The configuration for IPv6 is as follows (with garbled addresses):
   [ipv6]
   addr-gen-mode=stable-privacy
   address1=abcd:xyz:pqrs:1::1:41/64,fe80::9ec7:a6ff:fe0a:1f48
   address2=abcd:xyz:pqrs:1::1:54/64
   address3=abcd:xyz:pqrs:1::1:55/64
   dns=fd00::9ec7:a6ff:fe0a:1f48;
   dns-search=abcde.nl;fritz.box;
   ignore-auto-routes=true
   may-fail=false
   method=manual
   
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   journalctl -b shows error messages
   NetworkManager[472]: <warn>  [1534327996.6600] platform-linux:
   do-add-ip6-address[3: fe80::b8ae:b5ff:fe7f:5bfd]: failure 22 (Invalid
   argument)
   Before this error message I already have error messages about dovecot
   and apache2 not starting. The reason is that both have LISTEN
   statements listening on specific interfaces with an IPv6 address.
   Apparently bacause of the above error IPv6 addresses are not
   assigned. Also sshd and postfix are effected.
   I made workaround using crontab with @reboot for root to start a script which
   after a small delay sets IPv6 address and after another small delay restarts 
   the mentioned systemd services which need IPv6 addresses set.
   
   * What was the outcome of this action?
   The crontab works as expected.
   
   * What outcome did you expect instead?
   I expect nm to setup the proper IPv6 addresses and services that need
   these IPv6 addresses set to wait for this.
