sagemath broke aptitude

Postby jerryb on Tue Oct 08, 2013 9:25 am

I cannot refresh the list of packages.
I am told:
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_aims_sagemath_ubuntu_dists_quantal_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.

I would be happy to remove sagemath because one can now use it in its cloud.

However when I "sudo add-apt-repository --remove ppa:sagemath"

I get : "Cannot access PPA (https://launchpad.net/api/1.0/~sagemath/+archive/ppa) to get PPA information, please check your internet connection."
But internet is up, I'm writing this....................

When I "sudo aptitude purge sage"
I get:
[ ERR] Reading package lists
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_aims_sagemath_ubuntu_dists_quantal_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.

I don't know how to proceed.

Many thanks for your help

Thanks for the answer. I noticed that there were some complaints on the web that
sagemath is no longer an application for people to install if they don't already have it.

About my problem, I would like to remove sagemath from my system and get my usual updates of other programs.
Do you think that if I removed aims-sagemath-quantal.list and aims-sagemath-quantal.list.save from /etc/apt/sources.list.d/
that aptitude would be able to update other programs?

I think it is a failing of the system that one program's problems brings the whole system down.

Thanks again,

Jerry
