$ sudo aptitude versions matrix-synapse
[sudo] password for ac-adm: 
i   1.48.0-1~bpo11+1                                                       100

$ sudo aptitude why python3-authlib
i   matrix-synapse Suggests python3-authlib (>= 0.14.0)

$ sudo aptitude why python3-jwt
i   matrix-synapse Suggests python3-jwt (>= 1.6.4)

The -b option doesn't seem to be valid

$ sudo aptitude search matrix-synapse
i   matrix-synapse                  - Matrix reference homeserver              
i   matrix-synapse-ldap3            - LDAP auth provider for the Matrix homeser
v   python3-matrix-synapse-ldap3    -

That is the question, isn't it? Even with those packages installed,
there is still the issue with matrix-synapse-ldap3

$ sudo aptitude why matrix-synapse-ldap3
i   matrix-synapse Recommends matrix-synapse-ldap3

$ sudo aptitude why python3-frozendict
i   matrix-synapse Depends python3-frozendict (>= 1)

$ sudo aptitude search  python3-frozendict
i A python3-frozendict              - immutable dictionary - Python 3.x

In interactive aptitude, python3-frozendict is reported at 1.2-2, so it
looks like this is the explanation: 1.4.9 matrix-synapse requires 1.2-3.
Whether it is correct that this dependency prevents the upgrade to 1.49,
I don't know.

It doesn't seem right that matrix-synapse-ldap3 is a recommendation (not
a dependency) and yet...

After deleting and undeleting (from within aptitude)
frozendict is no loner marked as UNSATISFIED, the dependencies part only
says:

    --\ python3-frozendict (>= 1)
i A   1.2-2
p A   1.2-3~bpo11+1

But matrix-synapse still breaks matrix-synapse-ldap3 and the 1.49
version is still broken:

  --\ Versions of matrix-synapse (2)
id   1.48.0-1~bpo11+1                   -8,164 kB
pB   1.49.0-1~bpo11+2                   +8,288 kB

I don't know what else to try.
