I tried to see how hard it would be to load my current project in pharo7. Cyril helped me to see that I load an old version of zinc and it does not work that way. Upgrading to zinc 2.9.2 made it work in pharo 7 but my jenkins build do not work anymore. I donât fully understand what is happening. I see in the log Loading baseline of BaselineOfMobilityMap... ...RETRY->BaselineOfParasol ...RETRY->BaselineOfParasol[31mMessageNotUnderstood: ZnFileSystemUtils class>>newBinaryFileNamed:do: [0mZnFileSystemUtils class(Object)>>doesNotUnderstand: #newBinaryFileNamed:do: ZnClient>>downloadEntityTo: ZnClient>>downloadTo: IceMetacelloPharoPlatform(MetacelloPharoPlatform)>>downloadZipArchive:to: The strange thing about it is that when I download that image where the error occurred I cannot find a sender of #newBinaryFileNamed:do: and the #downloadEntityTo: does not seem to use it. Downgrading to zinc 2.8.10 makes it work again. I feel a little bit stupid because the image does not load any new package on startup and still there is this error message which does not make sense to me at all. Any ideas? Norbert
