If you use ZeroConf (get.pharo.org) scripts be aware that

  https://get.pharo.org/64/90+vm
  https://get.pharo.org/64/90+vmLatest

will lead to the trouble with the keyboard on Linux in Playground 
and other side effects.
 
So you have to use
    https://get.pharo.org/64/vmHeadlessLatest90 (VM only) 
or https://get.pharo.org/64/90+vmHeadlessLatest (VM+image)
 
which uses latest headless VM with 90 image and this is the one working
