Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

conflicting dependencies vagrant-hostsupdater (= 1.0.1) and vagrant-hostsupdater (= 1.0.2)
  Activated vagrant-hostsupdater-1.0.2
  which does not match conflicting dependency (= 1.0.1)

  Conflicting dependency chains:
    vagrant-hostsupdater (= 1.0.2), 1.0.2 activated

  versus:
    vagrant-hostsupdater (= 1.0.1)

  Gems matching vagrant-hostsupdater (= 1.0.1):
    vagrant-hostsupdater-1.0.1

how to get rid of that?

I tried removing/uninstalling all plugins and/or vagrant itself, how to proceed here?

I'll test this out locally.

Same on Fedora 33:
Vagrant failed to properly resolve required dependencies. These
errors can commonly be caused by misconfigured plugin installations
or transient network issues. The reported error is:

conflicting dependencies racc (= 1.4.16) and racc (= 1.5.1)
Activated racc-1.5.1
which does not match conflicting dependency (= 1.4.16)

Conflicting dependency chains:
racc (= 1.5.1), 1.5.1 activated

versus:
racc (= 1.4.16)

Gems matching racc (= 1.4.16):
racc-1.4.16
