在嘗試卸載 postgresql 時

sudo apt-get remove postgresql

我收到以下錯誤訊息

當我嘗試清除 postgres 時，也會發生相同的情況，這裡發生了什麼以及如何正確刪除 postgres？

答案1

你的問題

invoke-rc.d: initscript postgresql, action "start" failed.
dpkg: error processing package postgresql-common (--configure):
 subprocess installed post-installation script returned error exit status 1

我的解決方案

這短途

sudo rm /etc/init.d/postgresql
sudo rm /etc/init/postgresql.conf
sudo apt-get remove postgresql

或者很長的路要走

  • 開啟文件/var/lib/dpkg/info/postgresql-common.postinst

    sudo nano /var/lib/dpkg/info/postgresql-common.postinst

  • 使用啟動命令搜尋行：

    if [ -x "/etc/init.d/postgresql" ] || [ -e "/etc/init/postgresql.conf" ]; then
        invoke-rc.d postgresql start || exit $?
fi

  • 評論封鎖

    # if [ -x "/etc/init.d/postgresql" ] || [ -e "/etc/init/postgresql.conf" ]; then
#        invoke-rc.d postgresql start || exit $?
# fi

  • 再次取出包裝。

    sudo apt-get remove postgresql

解釋

在刪除 的過程中，會呼叫postgresql該腳本。postgresql-common.postinst該腳本嘗試啟動服務postgresql，但會失敗invoke-rc.d postgresql start（不要問我為什麼）。

必須防止這種情況發生。透過更改程式碼的執行條件。或透過刪除程式碼本身。
