OpenSTM32 Remote debugging support cannot be installed in the latest version of eclipse neon.
Yes, some features are no more provided by Eclipse Neon, while they were available in Mars; this mean we must change a bit our plugins to avoid the need for these. We’ve already looked at what it means but the correction will take some time before the correction is done, validated and pushed to the update site.
The next update of the plugins will probably avoid this problem, but other incompatibilities may exist with Eclipse Neon and clearing all issues may take some time.
Sorry for the delay but Neon is only out since a week ago...
