Comment 1 for bug 1605511

Please try packages from:

sudo add-apt-repository ppa:ci-train-ppa-service/2043
sudo apt update
sudo apt full-upgrade

With packages there, libica.so is still attempted to be loaded first. If that fails, libica.so.2 is attempted to be loaded, and that should succeed.

Before:
$ openssl engine ibmca
(ibmca) Ibmca hardware engine support
4396855273104:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:187:filename(libica.so): libica.so: cannot open shared object file: No such file or directory
4396855273104:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:233:
4396855273104:error:80066068:lib(128):IBMCA_INIT:dso failure:e_ibmca.c:1286:

After:
$ openssl engine ibmca
(ibmca) Ibmca hardware engine support
4396661810832:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:187:filename(libica.so): libica.so: cannot open shared object file: No such file or directory
4396661810832:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:233:

Which is still a bit ugly messaging, but should work out of the box.
