$ borg2 --version

$ ls -l /usr/local/bin/borg2

$ ssh foo@foo.example.org "ls /mnt/backup/borg2/"

It's empty, there's nothing in that directory...

$ ssh foo@foo.example.org "ls -l /mnt/backup/borg/foo/config
-rw-rw---- 1 foo foo 700 Nov 18  2020 /mnt/backup/borg/foo/config

That path exists and is a file. However:

$ borg2 --remote-path /usr/local/bin/borg2 --repo ssh://foo@foo.example.org:22//mnt/backup/borg2/foo repo-create --other-repo ssh://foo@foo.example.org:22/mnt/backup/borg/foo -e repokey-aes-ocb

No idea why borg2 is trying to access a nonexistent path /mnt/backup/borg/foo/config/readme as a directory?

(This bug is related to #8651 , since my workaround is to migrate to borg2...)

The new borg2 repo seems to get created however. No idea in which state it is though:

$ ssh foo@foo.example.org
  $ cd /mnt/backup/borg2 && ls
  foo
  $ du -sh /mnt/backup/borg2/foo/
  PLENTY OF GIGABYTES...

Guess --from-borg1 is missing (--other-repo is not only used for borg1 -> borg2, but could also be used for borg2 -> borg and the latter is the default).

Also there are different amounts of slashes for /mnt.

BTW, you shouldn't use borg2 for production (there is no beta-to-beta repo upgrade code).

Testing is of course welcome!
