a Maxima program running under the Windows implementation but not under Linux implementation of Maxima / wxMaxima

Hello Jochen,

I am happy to read that you got it work.

I found two pages in http://wiki.ubuntuusers.de about ppa. Perhaps these
can give a little bit more understanding on software sources and ppa.

I believe Ubuntu is not supplied via sourceforge because it is simply one
of hundreds of Linux distributions. The distributions maintainers are doing
a great job in resolving all dependencies. This should not be a task to the
Maxima developers.

Yes, the old version is overwritten. If you want it back, unflag the
repository from Istvan Blahota in synaptic and reinstall. But I guess you
won't.

Why don't you upgrade your Ubuntu?

Best
Volker van Nek
