Is it not possible to do a repository install for Squeak in Ubuntu derivatives anymore, independent from Scratch?

I noticed there is a squeak-vm in the repositories from Linux Mint 20.1 /Ubuntu 20.04, and so I tried to install it, to see how much of the knowledge I'm acquiring in a Pharo course is transferable to Squeak:

user@user-Standard:~$ apt-cache search squeak
squeak-plugins-scratch - Squeak plugins for the Scratch programming environment
squeak-plugins-scratch-dbg - Squeak plugins for the Scratch programming environment - debug
squeak-vm - virtual machine for Smalltalk
etoys - media-rich model, simulation construction kit and authoring tool
etoys-doc - documentation for Etoys
user@user-Standard:~$ sudo apt install squeak-vm

Now the curious thing is that it installs Scratch as well, even if I just requested Squeak.

When I look into the menu, it shows both Squeak and Scratch:

When I choose Squeak, a empty image selection screen is shown:

If I click the empty selection, nothing happens. It appears the squeak-vm is only a dependency for Scratch, and it's not possible to install it from the repository as a independent environment anymore. Am I right, or did I just do something wrong in the install process?

Solution

  • Part of the problem here is that the debian package (and since Ubuntu is derived from Debian as best I recall, I infer the Ubuntu package has the same issues) was created a long time ago and ... pretty much abandoned. Right now I believe it installs a vm built from the old-style interpreter sources, not the modern dynamic translator system.

    We (the Squeak community) are working on improving this.

    In the meantime it is much better to download packages from www.squeak.org
