Moving from an apt-get (Ubunto) install to Pybombs

Greetings, Long time lurker–daily user, but now faced with a
decision. I have noticed the fine work with Pybombs and picked up a more
hardware and thought to myself:“Hey, now is time to bite the bullet is
start using Pybombs” I don’t want that bullet to shoot me in the foot
(sorry). Question: What is the safest method to switch to Pybombs for a
working installation?My thoughts were to 1. Remove what I can manually
and start over2. Tell Pybombs to install into the ubunto
/user/local/blah dirs. Gregnz8r

Pybombs will only need root privileges to install missing libraries from
the Ubuntu archives.

I’d be a bit stronger than Marcus here and recommend that you definitely
remove any previous installations of GNU Radio. If you’ve gotten it
through
apt-get, then use apt-get to uninstall (and might as well purge) to make
sure you get it all and so apt-get isn’t confused about anything that
you’ve removed by hand.

While Marcus is right that the environmental setup from PyBOMBS will
provide a nice separation of everything, we still see a lot of problems
with double installs of GNU Radio, especially when they are installed
into
/usr.

Hi Greg,

pybombs is pretty safe. It will only install stuff that successfully
builds, so the chance that you wreck your installation are small, even
if you decide to install stuff into /usr/local. However, you can also
instruct pybombs to only install into /home/greg/prefix (or any other
directory of your choice), which will leave your whole system untouched.
You delete /home/greg/prefix, and everything pybombs did will be undone
:slight_smile:

You should indeed uninstall GNU Radio if you have already installed it,
but you don’t have to – the prefix method will work, nevertheless.
Pybombs will only need root privileges to install missing libraries from
the Ubuntu archives.
