GitLab ssh Benutzerzugriffsrechte

Ich habe eine Version von GitLab, die ich im letzten Herbst installiert habe. Leider kann ich keine Versionsnummer ermitteln. Es wird auf Ubuntu 1404 in einer VM auf einem Win10-Host gehostet. UPDATE: Sieht aus wie Version 9.4.3-ce.0 und ist die neueste Version, die von den Ubuntu-Paketservern verfügbar ist.

Ich erholte mich von einer Katastrophe, die eine kalte Neuinstallation von Win10 erforderlich machte. Ich habe die VM in VirtualBox installiert. Meine GitLab-Anmeldeinformationen scheinen einwandfrei zu funktionieren. Ich kann mich beim Server anmelden und meine Projekte mit http klonen. Was ich nicht tun kann, ist über SSH auf den Server zuzugreifen. Ich sollte hinzufügen, dass vor der Katastrophe alles gut funktioniert hat.

Von msys bash aus kann ich ssh einfach in die VM einbinden, aber alle Versuche, über ssh auf GitLab zuzugreifen, bewirken Folgendes:

$ git push origin dev-5-1-0 fatal: 'git@elm-ub1404/xxx/program.git' does not appear to be a git repository fatal: Could not read from remote repository.  Please make sure you have the correct access rights and the repository exists. 

Ich habe bestätigt, dass der Schlüssel in GitLabs Settings / ssh-keys der richtige ist. Ich habe es sogar gelöscht und dann wieder hinzugefügt, ohne Erfolg.

Die Protokolldatei gitlab-shell.log enthält Folgendes:

Aus irgendeinem Grund lösen meine Versuche, nach dem Löschen und Ersetzen des Originalschlüssels (gelöschter Schlüssel-1 und erneutes Eingeben als Schlüssel-3) auf das Repo zuzugreifen, keine Protokollnachrichten mehr in gitlab-shell.log aus.

Wenn ich "ssh -Tv git @ elm-ub1404" mache, erhalte ich Folgendes:

Meine Fragen sind also:

1. Wie bekomme ich weitere Informationen zur git-ssh-Verbindung?
2. Wie erhalte ich ssh wieder Zugriff auf GitLab?

AKTUALISIEREN:

Zur Sicherheit kopiere ich die Repo-Referenzen von der GitLab-Projektseite:
