I still get this error message when trying to do one-click upgrade from 0.5.1 to 0.5.4.
There was another fix in 0.5.3. Th update to 0.5.5 should be much smoother.
I faced the same issue today when I tried to update from 0.6 to 0.6.1.
Same problem here, going from 0.5.5 to 0.6.1.
dmaphy, klktrk, and others who may stumble upon here: This is fixed in . It'll be in the 0.6.2 release. For a quick fix, change CURLOPT_TIMEOUT to CURLOPT_CONNECTTIMEOUT in core/Http.php (or core/Piwik.php, if you have an older version).
This ticket is a different issue. Please direct any further comments to #1345. Thanks.
