axiom-configure fails due to missing 'packer' package on Ubuntu server 20.04.1

The following text is repeated forever:

Building image axiom... This can take up to 25 minutes so please be patient!
Ocassionally this will fail, we  don't know why, but it should auto-restart.
/root/.axiom/interact/axiom-build: line 46: packer: command not found
Your build failed :( Please take a look at the errors!
Builds may fail every now and then, there are some known bugs in Ubuntu Server that cause this.
Im sorry, but it just fails sometimes, just sit back and relax and we'll try again until  it works ;) 

The "packer" package is available in debian's, ubuntu's and arch's default repos. If someone can verify that manjaro, fedora and ubuntuwsl also have it in their default repos, I'll send a pull request to update axiom-configure.
