Comment 4 for bug 1908497

Please test this with 20.04 (tboot version 1.9.7-0ubuntu2) to see if the issue persists in 1.9.7).

I would presume that the 21.04 daily image (tboot version 1.9.12+hg20200718-1) will work correctly as it uses the same version you tried from sourceforge, but it would be nice if you could also test that 21.04 image to verify.

As this is a userspace package, you should also understand that to resolve this in either Bionic or Focal would require a SRU. Additionally, this is a Universe package which is not maintained by Canonical but rather is a community maintained project.

This would need a backport, as noted above, and that is a pretty strict process, so it may also be worth checking on the ubuntu-devel-discuss mailing list as noted under the "Maintainer" section of the tboot page on packages.ubuntu.com:
