Bugfixes on v1.31.0 repos [cryptography]

[AnonymousWebHacker]

I noticed that it is a bug that is fixed in v1.31.0rc1. https://github.com/matrix-org/synapse/releases/tag/v1.31.0rc1

• Bugfixes [Fix a bug introduced in Synapse 1.30.1 which meant the suggested pip incantation to install an updated cryptography was incorrect. (Fix the suggested pip incantation for cryptography #9699)]

Upgrade to 1.31 and it gave me that error. ;(
I tried to update the crypto version, but I don't know which version cryptography I should use with synapse 1.31
I read some issues but nothing clear, unless the cryptography had not been updated.

I am using repositories.
So? If it is only up to v1.30 for repos, am I going to have to wait until the update comes out?

@richvdh How can I see the version of Cryptography I can install so that it works with synapse v1.31 until it gets fixed in the repos?

this is a warning, not an error. Your problem lies elsewhere; check the homeserver log. If that doesn't help, try running synapse direct from the commandline rather than via systemd.

I'm going to close this issue as I think it is invalid; please use #synapse:matrix.org for support in getting Synapse set up.

(The CryptographyDeprecationWarning will be suppressed in Synapse 1.31 by #9698).

Fixed @richvdh
pip install -U cryptography
What happened is that they can be registered without problems, but for example, if I tried to enter from another section, it told me a cryptography error.

I had read your comments, and I know that this error that appears in the logs is a precaution and not an error in itself. Only that it did not let others start section, due to cryptography problems and the connection to the DB
