我在尝试升级到 Pop 时遇到了同样的“缺少 Pop.info”错误！操作系统 20.10。我能够通过以下过程解决它：

# Begin upgrade
sudo do-release-upgrade
# Pause the process with Ctrl-Z
^Z
# Create an empty Pop.info file in the newest /tmp/ubuntu-release-upgrader-* directory
sudo touch /tmp/ubuntu-release-upgrade-*/Pop.info
# Resume the upgrade process
