Can't install libssl.so.3 error

[aharbick]

I've tried to install this plugin and it fails (I believe) because pip can't find libssl.so.3. Any suggestions?

Looks like the plugin was already installed. Forcing a reinstall.

try this in SSH session of your pi.

https://askubuntu.com/questions/339364/libssl-so-10-cannot-open-shared-object-file-no-such-file-or-directory

[aharbick]

🤔 in not clear what you’re suggesting…. That I link a version 1.0 of the libssl lib to libssl.so.3? The problem in the linked post was that some code was incorrectly linking against libssl.so.10 but that it was actually the same version/dependency.

I think my case is a version mismatch for some reason…

[jneilliii]

I meant, just make sure it's installed.

sudo apt-get update
sudo apt-get install libssl libssl-dev

[aharbick]

Yeah. I ran that and it is installed. But it still can’t find libssl.so.3. I forced symlinks to that (as well as libcrypto.so.3) and then it fails trying to find OpenSSL 3.0 symbols. I think something has a dependency on a newer version of OpenSSL. 🤷‍♂️

[jneilliii]

yeah, the compiling side of libgcode is beyond me and prusa doesn't really give any good insight from their repo here for that module/library.

[aharbick]

Well thanks for looking anyhow! I build openssl3 from scratch with this https://hostnextra.com/learn/tutorials/how-to-install-openssl-3-on-ubuntu

and then I get a different linker error with libstdc++6

I’ll keep digging and see if I can figure something out and report back.

What fixed my octopi was ssh'ing into my pi and executing:

• sudo apt update
• sudo apt upgrade
