No but on released images we normally disable updates. Now you found a bug probably due to a change in Metacello

Pharo 2.0 + Seaside

by Chris

I would love to start using Pharo 2.0 but really need Seaside to be working. I'm assuming from what I've read that it is possible, but got some issues such as BlockContext missing, references to OmniBrowser, something about loading Metacello and when it finished there were 39 failures/errors in the tests. This was just from loading from the configuration browser in a fresh 2.0 image. Is there a better way? I like the look of the new system browser so far but it has felt a little sluggish in places. I hope this improves as I almost don't want to go back to OmniBrowser now :-) Cheers Chris

The file that you are trying to download (/ss/Pharo14/ConfigurationOfMetacello-dkh.709.mcz)) simply does not exist on the server in question (http://ss3.gemstone.com) Why the update process is trying to do that is another question.
