The tigervnc-standalone-server/1.9.0+dfsg-3+deb10u1 package is affected
by a bug in libunwind8 (Bug: #923962) exhibited on architectures arm64,
armel, and armhf that makes it unusable (Bug: #932499) on those architectures.

As a workaround, the proposed update tigervnc/1.9.0+dfsg-3+deb10u2
disables building against libunwind on exactly these three architectures.
Other architectures are not affected by the proposed update.
