Cadence not available in Mint 21 Vanessa

[kererubrewing]

I've just tried running your script on a new install (basic software updates, Nvidia driver install, installed gdebi and Chrome prior to running script). The error shown is:
`

Package cadence is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

E: Package 'cadence' has no installation candidate

`

I had thought it might be because I set my software sources to a local, New Zealand source, but returning to the default has not corrected this.

Any ideas on what might correct this? This looks very promising if I can get it to work (I am open to trying other versions of Linux if neccessary as I am in the evaluation stage of trying different Linux installs. My issue has been odd mouse behaviour (suspect scaling issues with display and Bitwig) and jerky UI responsivness and trying to smooth this out. Cheers.
