Comment 1 for bug 1683713

Hello,

We have also started to see the same issue starting today. We have network automated installs which are installing Ubuntu and these are now failing.

The issue is related to update-manager-core, version 1:0.196.23 is trying to be installed but only 1:0.196.11 is provided. Initially I suspected it could be due to the squid-deb-proxy we are using so I removed the complete cache but this didn't solve the issue. Also changed the links of the repositories, same issue.

On the system to be installed I can only see 1:0.196.11 when running apt-cache showpkg. On systems I have running for a longer time showpkg shows the 1:0.196.23 version:

---------------------------------------------------------

However, if I try to download this doesn't work:

------------------------------------
root@aaa:~# apt-get download update-manager-core
E: Can't find a source to download version '1:0.196.23' of 'update-manager-core:amd64'
------------------------------------

This works:

------------------------------------
root@aaa:~# apt-get download update-manager-core=1:0.196.11
Get:1 http://de.archive.ubuntu.com/ubuntu/ trusty/main update-manager-core all 1:0.196.11 [5,278 B]
