[Bug 1955114] Re: swtpm: upgrade to jammy fails

[Dimitri John Ledkov]

** Description changed:

+ [Impact]
+ 
+  * swtpm did not use to exist in ubuntu
+  * prior to packaging in ubuntu, it was common to compile and use swtpm debian packaging as provided by upstream
+  * ubuntu packaging is incompatible with upstream provided one, and upgrades to ubuntu package do not work automatically, despite same naming for some of the packaging
+ 
+ [Test Plan]
+ 
+  * build and install swtpm & swtpm-libs deb packages from
+ https://github.com/stefanberger/swtpm
+ 
+  * Attempt to upgrade to ubuntu's provided swtpm
+ 
+  * The upgrade should automatically break/replace and remove swtpm-libs
+ package that is not used in Ubuntu, and conflicts with swtpm package.
+ 
+ 
+ [Where problems could occur]
+ 
+  * Inverse change may be required in upstream packaging, if they wish to
+ support upgrading from Ubuntu packages to Upstream provided ones.
+ 
+ [Other Info]
+  
+  * Original bug report
+ 
+ 
  While trying to upgrade from impish to jammy I get:
  
  Preparing to unpack .../swtpm_0.6.1-0ubuntu5_amd64.deb ...

   * ubuntu packaging is incompatible with upstream provided one, and upgrades to ubuntu package do not work automatically, despite same naming for some of the packaging

   * build and install swtpm & swtpm-libs deb packages from

   * Attempt to upgrade to ubuntu's provided swtpm

   * The upgrade should automatically break/replace and remove swtpm-

  package.
