Ubuntu 22.04 has a openssl without ripemd160

[quartzo]

"electrum-sv" reports this error when trying to start on a Ubuntu 22.04 that uses a openssl 3..0.2:
ValueError: unsupported hash type ripemd160

It seems that the openssl maintainers decided to deprecate ripemd160.

Please provide the full error information.

Keep in mind that we do not have a dependency on openssl and our unittests run without error on Ubuntu 20.04.

Hi! Thanks for the reply.

Sorry about the reference to the 20.04 Ubuntu version, the new Ubuntu 22.04 is the one using the new openssl 3.0.2.
Electrum-sv is using hashlib from the standard python package, and Hashlib uses the openssl installed.

Rimemd160 was deprecated:
openssl/openssl#16994

Bitcoin-core implemented a python native solution:

Thanks for letting us know. I have opened an issue on the dependency we use for Bitcoin support.

[rt121212121]

Fixed in bitcoinx in develop branch. Do not use develop branch, it is not ready yet.

I am getting the same error with version 1.3.15. Is it supposed to be patched in this version?

There will be a 1.3.16 release soon, with a hack workaround.
