Many thanks nothing like doing an upgrade and finding all your automated scripts in Cron stop working.

Awesome, thanks! The sym-linking procedure worked for me using openssl 1.1 from macports.

Thank you! Fixed my problem with python 3.7.5 aborting.

@llbbl you know if this is reported to brew team?

@andresvia no not sure. Would be better for sure if they could fix this in ruby-land with a brew relink. Would be also interesting to figure out how the version numbers got added to critical openssl dependencies. Hopefully this will stop being a problem for everyone in the coming months.

All: Probably look at this issue: wbond/asn1crypto#158 and comment: Homebrew/homebrew-core#44996 (comment)

@andresvia so looks like deleting and/or upgrading asn1crypto to > 1.20 would also fix it? seems like a better approach to patching in some symlinks.

Yes @llbbl.

There are a lot of solutions out there, I'm going to post what worked for me.

At some point the pip3 command installed asn1crypto as dependency for another pip3 package, as mentioned by maintainer fxcoudert before the asn1crypto package is broken for Catalina before version 1.0.0 but pip3 uses cryptography functions, so pip3 also crashes, so it must be blasted manually.

I did:

mv ~/Library/Python/3.7/lib/python/site-packages/asn1crypto ~/Library/Python/3.7/lib/python/site-packages/nope-asn1crypto-nope

Then I just pip3 installed it again.

pip3 install --upgrade asn1crypto

I had no no more crashes after this.
