[Sugar-devel] Problem starting working with browse-activity

[James Cameron]

As you want to develop on the Python 3 or master branch of Browse, you
must have Sugar 0.116 installed for Python 3.  You can tell when that
is complete by running "python3 -c 'import sugar3'" without error.

You can do this with Ubuntu 18.04, but not with the user instructions
you referenced.  Those instructions are for using Sugar 0.112 with
Ubuntu, which is the only version Ubuntu have packaged, in turn
because Sugar 0.112 was the version packaged by Debian just prior to
the Ubuntu 18.04 freeze back in early 2018.  You will find that
"python2 -c 'import sugar3'" works without error.

Instead, you should use developer instructions.

https://github.com/sugarlabs/sugar/blob/master/docs/development-environment.md
are the developer instructions we maintain.  There are three sections.
The section "Packaged Sugar" will not work for you with Ubuntu 18.04,
as explained above.  So your choices are either "Sugar Live Build" or
"Native Sugar".

The former involves running another virtual machine.

The latter involves invasive changes to your Ubuntu 18.04 VM.  You're
welcome to follow those instructions, but if you are inexperienced in
any of the tools used there is a risk your VM won't be usable
afterward.

An alternative I've been working on recently is a set of packages to
add to the Ubuntu 20.04 operating system, which is yet to be
released.  The packages are available now, and I test them daily.

See my prior post on "Sugar for Ubuntu 20.04"
http://lists.sugarlabs.org/archive/sugar-devel/2020-February/057763.html

Of the three choices above, I don't know you well enough to suggest
any in particular.  Please review them all.
