In Debian:

python3-tornado | 6.0.3+really5.1.1-2 | testing | amd64, arm64, armel, armhf, i386, mips64el, mipsel, ppc64el, s390x
python3-tornado | 6.0.3+really5.1.1-2 | unstable | amd64, arm64, armel, armhf, i386, mips64el, mipsel, ppc64el, s390x

Currently PCS needs python3-tornado to be upgraded to 6 OR to have the fixes for 5.1.1 to be re-added.

Groovy:
Depends: ... python3-tornado (>= 6.0.4)
And
 python-tornado | 6.0.4-2 | groovy/universe | source

So fixed in groovy.

In Focal it is resolved as well even thou 6.x isn't 6.x

Focal:
Depends: ... python3-tornado (>= 6)
 python-tornado | 6.0.3+really5.1.1-3 | focal/universe | source

So the +really revert also resolved the bad dependency.
0.10.4-3 in Focal also has
  4 * d/p/Fix-python-tornado-5.patch: bring back workaround that fixes
  5 python-tornado until v6 becomes available

Closing this old bug
