Please provide termux-info output.

Try: pkg upgr -y.

deveee commented 2 years ago

Packages were mostly updated but now I checked after pkg upgr and the crash happens too.

And termux-info output was in previous comment, it was just copied without newlines from termux. I added these newlines for better readability.

And you can try it on some real files, for example transmission-cli https://cdimage.debian.org/debian-cd/current/amd64/bt-cd/debian-11.3.0-amd64-netinst.iso.torrent

transmission depends on RC4 algorithm which is moved to legacy provider on OpenSSL 3 and it is not loaded by default. There is a commit on the git master branch that transmission is switching to inbuilt RC4 implementation.

As a workaround, legacy_provider can be enabled via openssl.cnf so that RC4 algoriithm will be available for transmission.

I just updated the package and I successfully downloaded that debian iso from my previous comment, so it seems that it's now fixed.
