Ubuntu 20.04 Launcher error - cannot load such file

[hchesser]

Hello,

I have installed Ubuntu 20.04 (I have not installed Virtualbox as described in your video). I download and installed the tar file - there was a warning about ruby 2.5.8 (no longer supported). There was also an error that Cosmos now needs ruby => than 2.6.

At the end of the install I ran 'ruby Launcher' from the cosmos directory and get the message:

Traceback (most recent call last):
3: from Launcher:13:in <main>' 2: from /home/hugh/OpenSatKit-master/cosmos/tools/tool_launch.rb:14:in tool_launch'
1: from /home/hugh/.rbenv/versions/2.5.8/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in require' /home/hugh/.rbenv/versions/2.5.8/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in require': cannot load such file -- bundler/setup (LoadError)

I have tried upgrading ruby using the rbenv command to 3.2.2, but I get the same error.
