I use kali linux os , I have a problem with libcrypto.so.1.0.0 library

/Bureau/PacketTracer62Student/bin$ ./PacketTracer6 
./PacketTracer6: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory

You need to install libssl1.0.0:

sudo apt-get install libssl1.0.0

For future reference, you can install apt-file to find this out yourself:

sudo apt-get install apt-file
sudo apt-file update
apt-file search libcrypto.so.1.0.0
  • I get this Package libssl1.0.0 is not available, but is referred to by another package. – Deepak Kamat Oct 6 '18 at 9:17

Using reinstall worked for me:

sudo apt-get install libssl1.0.0 libssl-dev --reinstall
