[GNC] Up grade from 2.6.xx to 3.1

It is probbaly a good idea to uninstall the previous build of 2.6.x before
upgrading. With the changes between 2.6 and 3.1 there may have been changes
in the libraries/library names such that some older libraries may not
necessarilybe overwritten.

How to remove it will depend upon how you installed it and in which location
you installed it. If you built it from sources and you have retained the
source directory, try changing to the top level source directory or a build
directory if there is one in a terminal and then type 

make uninstall

if it was installed under your home directory

or sudo make uninstall

if it was installed to a system directory like /usr/local or/opt.

If you didn't retain the source directory and/or build directory then things
get a bit harder. One strategy would be to download the sources for that
version again. Follow the instructions for buidling that version apart from
the "make install" or "sudo make install" at the end. This will recreate a
manifest file. Then issue the "make install" or "sudo make install" in the
top level source directory (if you built them with a build directory then
issue the command in that build directory.)  Both Cmake and autotools can be
used on the later 2.6.x versions.

You can tell where Gnucash is installed using
whereis gnucash 
in a shell to list the locations that gnucash was installed to. If the first
part of the path is /usr/local or /opt or another system location ( that is
one not under the /home/dennis tree) then you will need to use sudo as a
prefix to make uninstall. I am not sure if whereis locates installs under
your home directory however.


If you installed using apt then

sudo apt-get remove gnucash
should do the job.

If you installed from a debian package you downloaded

sudo dpkg -r gnucash

should also remove it

There are instructions on the 

The BuildUbuntu16.04 wiki page has a section for Uninstalling Gnucash as
above. It also has a link  and a link to another which has instructions for
manually removing Gnucash. I need to add more to that page but the manual
removal instructions there do work. Note you need to use sudo before any
commands if installed in a system location.

I would try the instructions above first however as manually deleting things
from system directories 
can be hazardous to your system.

Cheers

David
