+Subject: Work around RSA SHA-2 signature issues in conch
+
+This was supposed to be fixed in Twisted upstream
+(https://twistedmatrix.com/trac/ticket/9765), and that fix is in Debian
+now. However, regression tests still seem to fail in GitLab CI but not
+locally (see e.g.
+https://salsa.debian.org/ssh-team/openssh/-/jobs/3513178). Leave this
+in place for now until we figure out what's wrong.
