ppa and libsuitesparse

Asked by Francis Poulin on 2016-01-21

Recently, I changed hte ppa for libsuitesparse-dev and am now using a non-standard version. See below.

 $ dpkg -l | grep libsuitesparse-dev
> ii libsuitesparse-dev:amd64
> 1:4.4.3-juliadeps1~utopic amd64 libraries
> for sparse matrices computations (development files)

I tried to return my ppa to the standard using this but this failed.

sudo ppa-purge ppa:bzindovic/suitesparse-bugfix-1319687

Can someone tell me how I can return to the default?

Thank you.

Hello again,

I figured out how to remove the ppa using the Software&Update window. That seemed to work.

But things have gone from bad to worst. I am very much wanting to install fenics but I can't because I have unresolved dependencies.

$ sudo apt-get install fenics

I tried to remove the packages, updating and upgrading but with no success.

I am following the instructions here.

Sorry for the trouble but any help would be greatly appreciated.

Ok, I think I figured out the problem.

Not sure why but there was a problem with libarpack2. When I removed it and then reinstalled it that seemed to fix it.

Sorry for the bother but glad it's working.
