voxel51 / fiftyone: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

Question

After installing and running fiftyone in python (using ubuntu 22.04), you get:

error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

Answer 1

[DISCLAIMER: credits for this answer should go here]

libcrypto.so.1.1 is part of the libssl package, which is by default version 3.* on ubuntu 22.04.

You don't want to override your default libssl installation just for running fiftyOne. Instead, you can download an older version and install it in an isolated location. For example:

$ mkdir $HOME/Software/openssl_1.1 && cd $HOME/Software/openssl_1.1
$ cd $HOME/Software/openssl_1.1
$ wget https://www.openssl.org/source/openssl-1.1.1o.tar.gz
$ tar -zxvf openssl-1.1.1o.tar.gz
$ cd openssl-1.1.1o
$ ./config && make && make test

Then before running your python program:

EXPORT LD_LIBRARY_PATH=$HOME/Software/openssl_1.1/openssl-1.1.1o

Why this near duplicate answer?

1. The error message emitted when running fityOne is different from here. So people looking for this specific error message may discard the existing question/answer as not relevant.
2. Also, the 'accepted answer' is not good practice. This attempts to rectify this situation.
3. People searching by the fityOne keyword will not land on the correct existing answer.
