Node crash on boot when ipv6 is disabled

If the ipv6 is disabled on the system, the node crashes on boot. I have it disabled, because of use of vpn.

Version

Broken in 4.6.0. In the version 4.5.2 it was booting fine.

How to reproduce (linux):

• sudo sysctl net.ipv6.conf.all.disable_ipv6=1
• start Deadalus

Error in developer console:

renderer.js:34 [2021-12-17T07:15:17.262Z] [daedalus.*mainnet*:error:ipcRenderer] {
  "msg": "AdaApi::getNetworkInfo error",
  "data": {
    "error": {}
  }
}

@dmitrii-gaico @danielmain After upgrading to 4.10.0#21740 , it works great with ipv6 disabled.

Thank you very much 🥇

I made a short oneliner to fix it temporary by commenting out the troublemaking line in the index.js file of the launcher

https://github.com/input-output-hk/daedalus/pull/2839#issuecomment-1079997820

I have made a oneliner to fix it temporary:

cd $HOME/.daedalus/nix/store && tmpfile=$(ack -l "concat\(args.listen.address6") && chmod 755 $(dirname "$tmpfile") && chmod 600 "$tmpfile" && sed -i "s+.concat(args.listen.address6+//.concat\(args.listen.address6+" "$tmpfile" && chmod 444 "$tmpfile" && chmod 555 $(dirname "$tmpfile") && tmpfile= && cd - && echo "IPv6 start parameter disabled"

• changes into the home directory of the user and subdirectory .daedalus/nix/store
• searches for the file that contains the specific line concat(args.listen.address6
• makes the directory and file temporary writable
• comments out the line in the file
• makes the directory and file readonly again
• changes back into the executing directory and displays a short message

If the little tool ack is not installed, install it first like typically:

sudo apt update && sudo apt install ack

Why does this take so long to fix it? Not skilled users will never be able to start Daedalus on such Systems.
