Hi there,

I am not sure what is wrong, but I did apt-get dist-upgrade and now I'm getting this:

deployer@TimeBox-1:~$ ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux-gnu]

deployer@TimeBox-972e24cfcf3c879f5500:~$ ruby
Traceback (most recent call last):
<internal:gem_prelude>:4:in `<internal:gem_prelude>': undefined method `gem' for main:Object (NoMethodError)
 1: from <internal:gem_prelude>:3:in `<internal:gem_prelude>'
<internal:gem_prelude>:6:in `rescue in <internal:gem_prelude>': uninitialized constant Gem::LoadError (NameError)

deployer@TimeBox-1:~$ gem update
Traceback (most recent call last):
<internal:gem_prelude>:4:in `<internal:gem_prelude>': undefined method `gem' for main:Object (NoMethodError)

I get this both for the stable 2.6.2 version and the experimental 2.6.5 from Brightbox packages. I'm on Ubuntu 18.04.3 on AMD64 arch.
