libgpg-error.so.0: no version information available

Question

I just started using ubuntu.

every time I want to start|stop|restart a service I get this error:

systemctl: /usr/local/lib/libgpg-error.so.0: no version information available (required by /lib/x86_64-linux-gnu/libgcrypt.so.20)

I did google but I could not find anything helps me.

I realized the problem after I did some changes to apache2 config file and needed to restart the service.

Answer 1

The problem is, you have an additional library in /usr/local/lib/:

/usr/local/lib/libgpg-error.so.0

Clarify why you have installed this library. Then you have two options:

1. Remove the library (backup)

   and your system takes the version in /lib/x86_64-linux-gnu/

   sudo mv /usr/local/lib/libgpg-error.so.0 /usr/local/lib/libgpg-error.so.0.bak
   

2. Remove the library and create a symbolic link

   if you need the library in /usr/local/lib/

   sudo mv /usr/local/lib/libgpg-error.so.0 /usr/local/lib/libgpg-error.so.0.bak
   sudo ln -s /lib/x86_64-linux-gnu/libgpg-error.so.0 /usr/local/lib/
