What you were trying to do (and why)

I am new to git, so if I am submitting the incorrect type of issue for this I apologize.
I was trying to use juju ssh to connect to a remote system.

What happened (include command output)

I failed to connect to the system and received the following response:

Command output

panic: cannot determine host series: unknown series version 20
goroutine 1 [running]:

What you expected to happen

I expected to connect to the machine. I did some looking and found that Juju hard codes os versions, and they came out with a quick fix the other day juju/os@1072051.

Step-by-step reproduction instructions (by running brew commands)

Output of brew config and brew doctor commands

### Brew Doctor:

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: A newer Command Line Tools release is available.
Update them from Software Update in System Preferences or run:
  softwareupdate --all --install --force

If that doesn't show you an update run:
  sudo rm -rf /Library/Developer/CommandLineTools
  sudo xcode-select --install

Alternatively, manually download them from:
  https://developer.apple.com/download/more/.


Warning: Some installed formulae are deprecated or disabled.
You should find replacements for the following formulae:
  sshfs

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  charm

Warning: You are using macOS 11.0.
We do not provide support for this released but not yet supported version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Twitter or any other official channels. You are responsible for resolving
any issues you experience while you are running this
released but not yet supported version.


Warning: Some installed formulae are missing dependencies.
You should `brew install` the missing dependencies:
  brew install python@3.9

Run `brew missing` for more details.

Yes, Juju is reproducibly currently broken on Big Sur due to the issue you mention. It's this bug on Juju's bug tracker, and we await a new juju release (2.8.7, according to the Juju devs) with the upstream fix that you linked.
