Hi there, it just tried to install Saros from the update site http://dpp.sourceforge.net/update from within Eclipse and got the following error after a while:
----- An error occurred while collecting items to be installed session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). Unable to read repository at http://downloads.sourceforge.net/dpp/de.fu_berlin.inf.dpp.core_0.1.0.jar?use_mirror=dfn. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target Unable to read repository at http://downloads.sourceforge.net/dpp/de.fu_berlin.inf.dpp.whiteboard_14.10.31.jar?use_mirror=dfn. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target ----- (Sabine encountered the same problem with all three jar files.) Eclipse's error log shows two "warnings", one for each jar file. These are followed by two "errors" -- again, one for each jar file. The stacktraces in all four log entries are identical: ----- javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed:

It can't be one of the URLs of our JAR files, as they all use the http protocol, which does not use certificates. Looking at the daily downloads [1], there seems to be a damp since 2017-01-23. It's not huge, but it could indicate that the problem exists since then. Any ideas, anyone?
