I noticed that it was a proxy server that stopped for installation after setting up a proxy server installed as a cream.
previous comment: After many attempts and attempts of another URL, finally found that the URL worked for me: http://beust.com/eclipse-old/eclipse-6.7.0.20120825_1316/
all other URLs continued to give an error for the MD5 example: An error occurred while collecting items to set the session context: (profile = epp.package.jee, phase = org.eclipse.equinox.internal.p2.engine.phases.Collect, operand =, action =). Problems loading the artifact: osgi.bundle, org.testng.eclipse, 6.9.11.201604020423. The MD5 hash was not as expected. Expected: da03b0c2cd24e2636ad05a151538b195 and found 60ea74539d11470e704c4210de6e5573. Problems loading the artifact: osgi.bundle, org.testng.eclipse.maven, 6.9.11.201604020423.
