Ubuntu 22.04 LTS升级至24.04 LTS时遭遇ppa-purge相关报错的解决求助

我想把Ubuntu 22.04 LTS升级到24.04 LTS，但不管是执行sudo do-release-upgrade还是sudo do-release-upgrade --allow-third-party，总会遇到下面的错误：

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This was likely caused by:

• Unofficial software packages not provided by Ubuntu
  Please use the tool 'ppa-purge' from the ppa-purge
  package to remove software from a Launchpad PPA and
  try the upgrade again.

我该怎么使用ppa-purge呢？我只是想顺利完成升级，这种不能直接升级的情况真的太烦人了。

执行ll /etc/apt/sources.list.d后得到以下输出：

deadsnakes-ubuntu-ppa-jammy.list
deadsnakes-ubuntu-ppa-jammy.list.distUpgrade
deadsnakes-ubuntu-ppa-jammy.list.save
