[Andreas Hasenack]

In saucy, upgrading from the current 12.12 release to the 13.07.1 SRU candidate fails due to a file conflict:

I suspect the SRU upgrade test that was done did not consider the two extra UI packages and only used landscape-{common-client}.

[Andreas Hasenack (ahasenack)]

State afterwards:
# dpkg -l|grep landscape-c
iU landscape-client 13.07.1-0ubuntu1 amd64 The Landscape administration system client
ii landscape-client-ui 12.12-0ubuntu3 amd64 The Landscape administration system client - UI configuration
iU landscape-client-ui-install 13.07.1-0ubuntu1 amd64 The Landscape administration system client - UI installer
iU landscape-common 13.07.1-0ubuntu1 amd64 The Landscape administration system client - Common files

A subsequent apt-get -f install fixes it, but if you are using landscape to manage this computer you are in trouble, because the client isn't running anymore.
# apt-get -f install

Looks like I forgot a Breaks: stanza in the debian control file (landscape-client-ui should break landscape-client).

I will make sure this works in here https://launchpad.net/~tribaal/+archive/landscape-client/
before I push a -0ubuntu2 to the staging PPA.

[Chris Glass (tribaal)]

The landscape-client 13.07.1-0ubuntu2 package was pushed to the staging archive, marking as fix committed.
