I fixed the problem manually, just writing my process down in case anyone else has the same problem.
Steps I took that resulted in the problem:
I downloaded the Ubuntu bit archive from Fritzing website, extracted to my local and ran ./Install and ./Fritzing
The error was “error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory”
…
What I expected should have happened instead:
Fritzing normal startup
…
My version of Fritzing and my operating system:
Fritzing 09b from Fritzing website
Ubuntu Studio 19.04
…
Please also attach any files that help explaining this problem
Don’t worry I fixed it!
So I got the missing libssl from Debian repo here: https://packages.debian.org/jessie/amd64/libssl1.0.0/download
Edit: run dpkg --install filename.deb after downloading it
It was not available through apt on Ubuntu 19.04 - I believe they have replaced this library with a newer one (most likely almost exactly the same thing with a new version number, so you could probably link it up)
If I am incorrect in my assumptions here please correct me. Anyway Fritzing is up and running again for me at least.
