After installing Unity Game Engine, I tried to run it by its launcher but no any window appears. Then, I tried to run it in the terminal and got the following error message.
$ ./Unity
./Unity: /opt/Unity/Editor/Data/Tools/libgpg-error.so.0: no version information available (required by /lib/x86_64-linux-gnu/libgcrypt.so.20)
./Unity: relocation error: /lib/x86_64-linux-gnu/libgcrypt.so.20: symbol gpgrt_lock_lock, version GPG_ERROR_1.0 not defined in file libgpg-error.so.0 with link time reference
How to fix it?
go to this path Unity/Editor/Data/Tools/libgpg-error.so.0 and remove libgpg-error.so.0
