为什么在使用配置的 squid-deb-proxy 客户端从 19.10 到 20.04 LTS 运行 do-release-upgrade 时出现“身份验证失败”？

  • 772

我正在squid-deb-proxy本地网络中运行服务器。在运行所有 APT 命令时，它适用于所有包下载。它针对镜像的所有可能已知 URL 进行配置，包括old-releases。Ubuntu 19.10 客户端已安装客户端 -squid-deb-proxy-client软件包。

$ dpkg -l squid-deb-proxy-client | tail -n1
ii  squid-deb-proxy-client 0.8.14+nmu2  all          automatic proxy discovery for APT based on Avahi

但是当我尝试开始升级过程以获得 20.04 LTS -sudo do-release-upgrade在终端中使用时，我收到以下错误消息：

$ sudo do-release-upgrade

squid-deb-proxy我在服务器端的日志中没有看到任何特别之处：

我应该如何解决身份验证无法通过代理服务器正常运行升级的问题？我不想关闭代理服务器（或从客户端排除其配置）来解决问题。

笔记：

  1. 对于可能的近距离投票者：当我尝试使用sudo do-release-upgrade -d.
  2. 我已向启动板报告错误 1888058。
  3. 删除deb-package 并通过insquid-deb-proxy-client指定代理不会改变任何内容。Acquire::http::Proxy "http://192.168.12.34:8000";/etc/apt/apt.conf
upgrade apt proxy 20.04 19.10

  1. 此问题与您的 squid 代理无关。它无法将下载的文件“focal.tar.gz”与文件“focal.tar.gz.gpg”中的 GPG 密钥匹配。

    此问题已解决：https ://stackoverflow.com/a/62463184/1525392

    正如 Hiren 建议的那样，您必须在其中替换为以下内容

    /etc/apt/sources.list

    但是在替换之前一定要备份这个文件。

    deb http://in.archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse

deb http://in.archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://in.archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse

deb http://in.archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse

deb http://archive.canonical.com/ubuntu focal partner
deb-src http://archive.canonical.com/ubuntu focal partner

    然后，

    sudo apt-get install --reinstall ubuntu-keyring

  2. Best Answer

    这里的问题是由于我的代理具有旧版本的安装程序文件这一事实引起的。

    所以我通过客户端上的命令触发手动缓存更新来解决这个问题：

    cd /tmp
http_proxy=http://192.168.12.34:8000 wget --no-cache -c http://archive.ubuntu.com/ubuntu/dists/focal-updates/main/dist-upgrader-all/current/focal.tar.gz
http_proxy=http://192.168.12.34:8000 wget -c http://archive.ubuntu.com/ubuntu/dists/focal-updates/main/dist-upgrader-all/current/focal.tar.gz

    在服务器上：

    sudo service squid3 restart
sudo service squid-deb-proxy restart

    然后升级运行良好。
