#165531 — weak repository key

FromFloris <jkfloris@dds.nl>

Subjectweak repository key
Message-ID<rdIv8-Qo-19@gated-at.bofh.it>
After updating to apt version 1.2.7 I get a warning on apt-get update:
W:  
gpgv:/var/lib/apt/lists/partial/dl.google.com_linux_chrome_deb_dists_stable_Release.gpg:  
The repository is insufficiently signed by key  
4CCA1EAF950CEE4AB83976DCA040830F7FAC5991 (weak digest)

and the repository is ignored

Is there a way that apt re-trust the old SHA1 key, or do we have to report  
this to Google and all other repos?

According to
https://bugs.chromium.org/p/chromium/issues/detail?id=594414 this should
be fixed with the next repository update.

Well, Google has not fixed this, so of course you still have the
problem. But there is _nothing_ Debian can do here.

The bug is at
<https://bugs.chromium.org/p/chromium/issues/detail?id=596074> and has
not seen much action.

But since Ubuntu Xenial 16.04 will release with an apt version also
showing this warning, I guess this will get a lot more traction as soon
as Xenial is released because a lot more "normal" people will then get
the warning and not just people running Debian Testing/Unstable or
Beta-Versions of Ubuntu.

Grüße,
Sven.

The list of repositories which are known to have this problem is
available here:

https://wiki.debian.org/Teams/Apt/Sha1Removal

The only way for the problem to be fixed, short of reverting the
software feature change which introduced it (which would reintroduce
security weaknesses), is for the people who run those repositories to
re-sign their files as described on that page.
