我在嘗試升級到 Pop 時遇到了同樣的“缺少 Pop.info”錯誤！作業系統 20.10。我能夠通過以下過程解決它：
# 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 fg
除了@cwc 的回答，
# Begin upgrade sudo do-release-upgrade # Pause the process with Ctrl-Z ^Z # Find the tmp folder that newly created. And store LAST_CREATED_FOLDER variable. LAST_CREATED_FOLDER=$(sudo ls -t /tmp/ | grep ubuntu-release-upgrader | head -1) # Create an empty Pop.info file in the newest /tmp/ubuntu-release-upgrader-* directory sudo touch /tmp/$LAST_CREATED_FOLDER/Pop.info # Resume the upgrade process fg
