[solved] Can not upgrade to 2.7 (error 404)


I am trying to upgrade to Yunohost 2.7 but it fails while contacting a package url :

root@xxxxx:~# yunohost tools update
Traceback (most recent call last):
  File "/usr/bin/yunohost", line 217, in <module>
  File "/usr/lib/python2.7/dist-packages/moulinette/__init__.py", line 139, in cli

    if not cache.update():

    raise FetchFailedException(e)
apt.cache.FetchFailedException: W:Failed to fetch http://swupdate.openvpn.net/apt/dists/jessie/main/binary-i386/Packages  404  Not Found [IP: 80]
, E:Some index files failed to download. They have been ignored, or old ones used instead.

It was an issue with my /etc/apt sources directory issue ; sorry about that
