/var/cache/debconf/config.dat-new:权限被拒绝

Question

当我运行这个时，我得到了debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission deniedndebconf: DbDriver "config": could not write /var/cache/debconf/config.dat-new: Permission deniedn#> [packages]: Packages : FAILn"。看起来它不是出于某种原因

。

(ns localhost.idk
  (:require (pallet [compute :as compute]
                    [api :as api :refer [lift]]
                    [actions :as actions])))
;; Running this on my local machine
(def my-data-center
  (compute/instantiate-provider
   "node-list"
   :node-list [["localhost" "ed" "127.0.0.1" :ubuntu
                :is-64bit nil]]))
(def user-deadghost
  (api/make-user "deadghost"
                 :password "my-pw"
                 :sudo-password nil)) ; pwless sudo set up
(defn install-ed []
  (pallet.api/lift
   (pallet.api/group-spec
    "ed"
    :phases {:configure (api/plan-fn
                         ;; This works:
                         ;; (pallet.actions/exec-script
                         ;;  ("sudo aptitude install ed"))
                         ;; This is trying to run without sudo:
                          (actions/packages :aptitude ["ed"]))})                         
                         ;; log shows: p.script-builder prefix kw :no-sudo
   :compute my-data-center
   :user user-deadghost))

它正在运行的脚本：

#!/usr/bin/env bash
mkdir -p /home/deadghost || exit 1
cd /home/deadghost
set -h
echo '[packages]: Packages...';
{
    { debconf-set-selections <<EOF
debconf debconf/frontend select noninteractive
debconf debconf/frontend seen false
EOF
    } && enableStart() {
        rm /usr/sbin/policy-rc.d
    } && apt-get -q -y install ed+ && dpkg --get-selections
} || { echo '#> [packages]: Packages : FAIL'; exit 1;} >&2 
echo '#> [packages]: Packages : SUCCESS'
exit $?

我收到的错误与没有sudo的debconf部分一致。

截至pallet 0.8.0-RC.11在本地主机上运行时，默认脚本前缀为:no-sudo默认值:sudo。这是出于历史原因，我不知道细节。

要将脚本前缀更改回 sudo ，请使用 (pallet.action/with-action-options {:script-prefix :sudo} YOUR-ACTION-HERE) 包装您的操作。所以在我的情况下，它看起来像这样：

(defn install-ed []
  (pallet.api/lift
   (pallet.api/group-spec
    "ed"
    :phases {:configure (api/plan-fn
                         (pallet.action/with-action-options
                           {:script-prefix :sudo}
                           (actions/packages :aptitude ["ed"])))})
   :compute my-data-center
   :user user-deadghost))
