Re: [wtp-dev] Helo with Egit error when accessing a repo using ssh

Roberto,

Things started working for me once this bug was resolved last week - https://bugs.eclipse.org/bugs/show_bug.cgi?id=463793.

A co-worker was still having difficulties, but after updating to Luna SR2 they had success.  I assumed this was due to getting a newer version of EGit.  I cleared out my eclipse.org hosts from known_hosts as a precaution.

Hello, this question is not specific to WTP, but I wanted to try asking here, since Egit is used among WTP contributors.

Since last week, when I try to pull or push to any of the webtools repository for which I'm commiter using Egit, I get this error:

Has anybody else seen this error? Any advice/suggestion?

I know there were changes in the eclipse.org keys, so I updated the contents of my known_hosts file, but I still see the same error.

Pushing/pulling works fine if I use git command line.

I'm using Egit 3.7.0.201502260915-r, and I have tried different versions of Java 7 and 8, and different vendors.


Regards,

Roberto Sánchez Herrera
