Upgrading +only “puppetmaster” upgraded “puppet-common” but not “puppet,” causing Apt to +remove “puppet”; upgrading only “puppet” similarly upgraded “puppet-copmmon” +but not “puppetmaster,” causing Apt to remove “puppetmaster.”</p> +<p>The Puppet aptitude provider (which I use instead of apt-get) for Package +resources also doesn't know how to tell aptitude what to do with config files +during upgrades. This prevented Puppet from being able to upgrade pacakges +even when running standalone (via <code>puppet apply</code>).</p> +<p>Finally, something about the switchover from Canonical's Puppet .debs to +Puppetlabs' .debs caused aptitude to consider all three packages “broken” +after a manual upgrade ('aptitude upgrade puppet puppetmaster'). Upgrading the +packages a second time corrected it; this is the path I eventually took with +my production puppetmaster and nodes.</p> + </div> + + + +<div id="comments"> +<div id="disqus_thread"></div> +<script type="text/javascript"> + /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ + var disqus_shortname = 'grimoire'; // required: replace example with your forum shortname + + /* * * DON'T EDIT BELOW THIS LINE * * */ + (function() { + var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; + dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js'; + (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); + })(); +</script> +<noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> +<a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a> +</div> + + + + <div id="footer"> + <p> + + The Codex — + + Powered by <a href="http://markdoc.org/">Markdoc</a>. + +<a href="https://bitbucket.org/ojacobson/grimoire.ca/src/master/wiki/devops/puppet-2.7-to-3.1.md">See this page on Bitbucket</a> (<a href="https://bitbucket.org/ojacobson/grimoire.ca/history-node/master/wiki/devops/puppet-2.7-to-3.1.md">history</a>). + + </p> + </div> + +</div> +</body> +</html>
