Which action should I take: (a) go back to using Racket v.7.7 or (b) resolve issues.

[infodeveloperdon]

I'm nervous. After installing racket version 7.8 on linux (Ubuntu) at a time when I really should not have done only because I'm in the middle of development and would much prefer to change the version at a later date.  The installation did not go without a hitch this time, meaning the problem seems to be minor but will take me time to resolve. I am inclined to return to version 7.7, if that is possible.

Q. Is it a mistake to simply reinstall racket v.7.7? Does that action make it the current version even though version 7.8 is now installed.

Q. To change the current racket version should I be using:

a)  raco setup...

or possibly:

b)  raco pkg remove

and

      raco pkg install

Q. I've been reading up on "Getting Started with Packages" but am I correct in thinking they are conceptually within a racket version rather than the complete definition of a racket version.

Thanks

Don

On Linux it's better to uninstall the current version before installing
another (unless you want to install multiple versions in parallel).  The
main thing is to AVOID a "Unix-style" installation which sticks things
in many different places.

Sorry, I don't have a lot of use for packages that aren't included in
the distribution, so I can't help you here.  If you have installed extra
packages, they DO need to be migrated into (recompiled for) a new Racket
version.

If you install multiple versions of Racket (in different directories),
you can just modify your path to reference the one you want.  Or if you
use DrRacket, create multiple launchers - one for each version.
