Because indico (3.3.4) depends on flask-multipass (0.5.5)
 and indico (3.3.2) depends on flask-multipass (0.5.4), indico (3.3.2 || 3.3.4) requires flask-multipass (0.5.4 || 0.5.5).
And because no versions of indico match >3.3.1,<3.3.2 || >3.3.2,<3.3.3 || >3.3.3,<3.3.4 || >3.3.4,<4
 and indico (3.3.1) depends on flask-multipass (0.5.4), indico (>=3.3.1,<3.3.3 || >3.3.3,<4) requires flask-multipass (0.5.4 || 0.5.5).
And because indico (3.3.3) depends on flask-multipass (0.5.4)
 and flask-multipass[saml] (0.6) depends on flask-multipass (0.6), flask-multipass[saml] (0.6) is incompatible with indico (>=3.3.1,<4).
So, because flask-multipass-saml-groups depends on both flask-multipass[saml] (0.6) and indico (>=3.3.1, <4), version solving failed.
