This commit makes to use python3-guestfs instead of python-guestfs in Ubuntu because python-guestfs package is not provided in focal[1][2]. This causes errors in some gate job if `ENABLE_FILE_INJECTION` is true like the following. ``` ... Package python-guestfs 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 However the following packages replace it: python3-guestfs E: Package 'python-guestfs' has no installation candidate ... ``` http://paste.openstack.org/show/801073/ [1] https://packages.ubuntu.com/search?lang=en&keywords=python3-guestfs [2] https://packages.ubuntu.com/search?lang=en&suite=default&arch=any&searchon=names&keywords=python-guestfs Change-Id: Iffe60aa0351b732d543927afa1f1e846ba2a89fd
