Failed to get annex.uuid configuration of repository clam Instead, got: "(merging origin/git-annex origin/synced/git-annex into git-annex...)\n(recording state in git...)\nannex.uuid=$obscured\ncore.gcrypt-id=\n"
Seen after cloning the repository to clam, not running git-annex init in it, adding clam as a remote, and git annex sync clam. Apparently git-annex-shell outputs some merging messages in this case, which breaks the protocol.
Next git-annex sync clam worked ok and got the UUID.
clam has git-annex 6.20170101 installed. --Joey
