I’m using MacOS X 10.11.6 and the newest OH2 release.

When trying to install in Paper UI additional packeges like EXEC-Biding or Mail-Action or Telgram-Action the following massage appears in the log:
12:58:04.566 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-action-telegram, openhab-binding-exec, openhab-action-mail': Error

Here is more prices warning when installing Exec-Binding:

It seams that I need to upgrade a file which contains correct binding information. I.e. the process is trying to download “2.0.0-SNAPSHOT” which doesnt exist anymore. Instead “2.0.0” should be used.
Does anybody knows a resolution?

I meet the same issue, after a fresh install of openHAB 2.0.0 Release onto a freeBSD OS.
So I’m searching an answer also and I’m taking any idea.

I solved my issue. The reason for it was that although I’ve done a fresh install, I’ve then copied /config and /userdata from a previous version. This is not working. It seems that especially /userdata must be somehow recreated by a new version. Hence I done again a fresh install and took /config and /userdata/persistence only (to save the database) from the old version.
