Usually ssh key problem of it means borg is not installed on the server

BlockingIOError: [Errno 11] Resource temporarily unavailable

windows?

Corrupted segment reference count - corrupted index or hints

For some reason it might help to run

borg check --repository-only

Exception: FD exception occurred

Probably running borg on cygwin, could be ssh key issue. Try

BORG_RSH="ssh -vvv" borg ...

Also check your quotes

Cache, or information obtained from the security directory is newer than repository - this is either an attack or unsafe (multiple repos with same ID)

Something broke during a backup, try (re)moving ~/.config/borg/security/<id> and ~/.cache/borg/<id>.

Prune: Chunk ID missing from chunks index, corrupted chunks index - aborting transaction.

Try

borg check ( --repair )

If check finds no problem, delete cache:

mv ~/.cache/borg ~/.cache/borg_corrupted

ValueError: stats_against: key contained in self but not in master_index.

Try

borg check ( --repair )
