linux - Azure 云初始化 : Failed to install packages

Question

我有一个简单的 cloud-init 文件:

#cloud-config
package_upgrade: true

packages:
  - symlinks
  - wget
  - rsync
  - git

但我的 Azure 失败(最后提供日志)。
这是我第一次在 Azure 上使用 cloud-init。
可能出了什么问题以及如何修复它？

PS。我的虚拟机:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:    11
Codename:   bullseye

$ uname -rm
5.10.0-6-cloud-amd64 x86_64

Answer 1

较新版本的 apt 使用选项字符串，因此您可以延长超时并向命令添加重试。例如:

sudo apt update -o Dpkg::Lock::Timeout=60 -o Acquire::Retries=60

您可以将其包含在云配置文件中。 (示例 cloud-init 文件。)

apt:
  conf: |
    Acquire::Retries "60";
    DPkg::Lock::Timeout "60";

这将创建一个文件/etc/apt/apt.conf.d/94cloud-init-config。这些选项有助于避免 waagent 竞争时立即出现锁定错误。

其他信息:

• man apt.conf
• ls/usr/share/doc/apt/examples/
• cloud-config-apt.txt
