ubiquity in Ubuntu 20.04 Deprecation warning

[MikeR]

Running ubiquity after an upgrade fom 18.04 to 20.04 LTS ubuntu:
/usr/bin/ubiquity:74: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp

Note: Replacing "imp" by "importlib" in /usr/bin/ubiquity does NOT work.
ubiquity appears to succeed, are there any latent issues which might crop up following this warning?

This bug was fixed in the package ubiquity - 21.04.4

---------------
ubiquity (21.04.4) hirsute; urgency=medium

  [ Jean-Baptiste Lallement ]
  * Moved from deprecated sip4 to sip from PyQt5 (LP: #1903378) Thanks Rik
    Mills for the references.
  * Replaced deprecated module imp by importlib (LP: #1898494)

  [ Shih-Yuan Lee (FourDollars) ]
  * set() has a random order when looping it that makes the failure of
    dependencies issue random. Sort the list of package to make it predictable
    and easier to diagnose dependency issues.

  [ Łukasz 'sil2100' Zemczak ]
  * Provide some minimal user feedback on the UI when ubuntu-drivers is busy
    while running in the background. (LP: #1824905)

  [ Gunnar Hjalmarsson ]
  * d-i/patches/localechooser-post-base-installer.patch:
    - Set nl (Dutch) as the default Belgian language (LP: #1907914)
