Seit dem heutigen Dist-Upgrade werden in der Ausgabe von apt update Warnungen für Repos von Dritten auftauchen. Dies sind keine Fehlermeldungen. Hier etwas Hintergrund: http://www.pro-linux.de/news/1/23358/debian-und-ubuntu-vertrauen-sha1-nicht-mehr.html


----


Since todays dist-upgrade APT does not trust signatures from SHA1 anymore. That will lead to warnings in apt update for third party repos that are not trusted anymore until they up their security using SHA2 or 3 or some other trusted hash function. My above link also holds 2 links in EN for fürther detail.

Hallo @devil,

vielen Dank für die Meldung.
Ich habe gestern erst ein dist-upgrade durchgeführt und keine Fehler vorgefunden.
Es liegt wohl daran das ich nicht viele zusätzliche Quellen im System aktiviert habe, nur solche die Vertrauenswürdig sind.

Vetrauenswürdig gegenüber wem? Debian vertraut derzeit weder Google oder Steam, openSuse oder irgendeinem anderen Drittrepo. Falls Du noch kein APT 1.2.7. hast, wirst Du auch nichts bemerken.

Du hast mal wieder recht, ist noch Version 1.2.6, habe aber auch kein Update zur Auswahl.

Code: [Select]
root@siductionbox:/home/deka# apt-cache policy apt
apt:
  Installiert:           1.2.6
  Installationskandidat: 1.2.6
  Versionstabelle:
 *** 1.2.6 500
        500 http://ftp2.de.debian.org/debian unstable/main amd64 Packages
        500 http://ftp.de.debian.org/debian unstable/main amd64 Packages
        500 http://ftp.is.debian.org/debian unstable/main amd64 Packages
        100 /var/lib/dpkg/status
/

Habe ein apt update vergessen, mein Fehler.

Hi All,

I reached out to the Insync support team let them know that their about their Sid repo using SHA-1 and they have fixed it. 

assuming you are using the following repo.

Code: [Select]
deb http://apt.insynchq.com/debian sid non-free contrib
Now they haven't made these changes to there Jessie or Wheezy repos.

Gibt es für Google noch eine andere Quelle?
Code: [Select]
update-pepperflashplugin-nonfree --install --unverified --beta

I have tried the following patch for this, and it works:   https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=818540#20
From what I gather of the thread, this patch should be part of its next release.

I've been getting the warnings on my machine for the Videolan and Vivaldi repos for the past 10 days.  I just haven't made time to look into the issue.  Thank you for the heads up, devil, and thank you also for translating your post in English.
