Thank you @dyrnq for reporting this, and you @PabloCastellano for reporting all of that information!
I will add a note in the installation page. There's not much we can really do at this point.

I'm getting the same issue on Pop!_OS ( Ubuntu ) 20.04 LTS.

Is it possible we could reduce the required glibc version to the older version, or otherwise bundle glibc 2.32 in the lib folder with the distribution?

@Random72IsTaken commented on GitHub (Jun 17, 2022):

I did this on Ubuntu 22.04.

When I first launched the Linux built app, got the blank window.
Ran the app through the terminal: ~/Downloads/AppFlowy/app_flowy and saw the libssl whatever not being found.
Then ran ldd ~/Downloads/AppFlowy/lib/libdart_ffi.so which was first read to reach the error and shown the missing 2 library links, which Ubuntu has new versions of:
```
libssl.so.1.1 => not found
libcrypto.so.1.1 => not found
```
So now I needed to see if the exact versions are available somewhere, and ran sudo find / -name "libssl*", which had found that that torguard app has them in its lib directory!
I also understood that LD_LIBRARY_PATH variable is used to find those libraries and initially echoing it has an empty result!
So I first tried to run the app counting those libraries in LD_LIBRARY_PATH="/opt/torguard/lib" ~/Downloads/AppFlowy/app_flowy and it worked!
Now I copied them the 2 libraries to /usr/local/lib, then touched 2 conf files for them like so:
- sudo nano /etc/ld.so.conf.d/libcrypto.so.1.1.conf with only /usr/local/lib inside.
- sudo nano /etc/ld.so.conf.d/libssl.so.1.1.conf with only /usr/local/lib inside.
Now just had to export LD_LIBRARY_PATH="/usr/local/lib, I guess, then run sudo ldconfig to save it all! 😋
