The error message mentions (perhaps not very clearly) that the shared
library installed with the gsl R package could not be loaded. Chances
are that the gsl package (and as a consequence the copula package, too)
didn't work before you upgraded. This can happen e.g. if the dependent
system library (libgsl-dev?) is upgraded.
update.packages() doesn't try to load any packages, which would be
necessary to detect this scenario.

Did you reinstall the gsl package [1]?
Apparently not. I did a complete update.packages() which reinstalled a
great number of packages (I have a great number in my personal library).
There were complaints about 4 packages, one of which was "copula", but
"gsl" was not one of them.
I would have *thought* that if "gsl" needed to be reinstalled, then
update.packages() would have done this.
It also makes no sense to me --- the install of "copula" complained
about not being able to find a shared object library (presumably of
fortran or C or some such code), not about being unable to load "gsl".
Be that as it were, I did an install (a reinstall) of "gsl"
successfully and then the install of copula was also smooth and
successful.
Thanks.
cheers,

I have just upgraded to the latest R (3.3.2) and thought I should
update my library of contributed packages.
Ran into problems with "copula". Got the error:
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/home/rolf/Rlib/gsl/libs/gsl.so':
libgsl.so.0: cannot open shared object file: No such file or
directory
So after a bit of googling around I did:
sudo apt-get install libgsl2
sudo apt-get install libgsl-dev
both of which ran successfully.
Still no joy, but. What *else* do I need to do?
I am running Ubuntu 16.04.1.
