从 20.04.02 LTS 升级到 22.04.1 LTS 时出现 UnicodeDecodeError

我尝试使用 GUI 更新管理器工具从 20.04 升级到 22.04。但仅在第一步之后它就一直崩溃。因此我尝试通过 CLI 运行命令进行升级sudo do-release-upgrade -d。但我收到以下错误：

我尝试了在互联网上找到的每一个答案，但没有成功:(。请帮助解决此错误。

答案1

以下是一条链接带有手册。

文件“/tmp/ubuntu-release-upgrader-l3yamuwr/DistUpgrade/DistUpgradeQuirks.py”，第 395 行，位于 _test_and_fail_on_pam_tally

这是出现错误时正在运行的升级程序脚本。编辑该文件（以 root 身份）并转到第 395 行，您会发现自己处于“for”循环中：

   for f in os.listdir('/etc/pam.d'):
       if f in ('common-account', 'common-auth', 'common-password',
                'common-session', 'common-session-noninteractive'):
           # managed by pam-auth-updates, and any references to
           # pam_tally* will be handled by libpam-modules on upgrade
           # without breaking
           continue
       with open(os.path.join('/etc/pam.d', f)) as f:
           content = f.read()
           if re.search('^[^#]*pam_tally', content, re.MULTILINE): <--- >line 395
       <snipped>

该脚本正在循环遍历 /etc/pam.d 中的文件。您可以去那里查找问题，也可以编辑脚本以查找在出现错误时正在处理哪个文件。如下所示：

    with open(os.path.join('/etc/pam.d', f)) as f:
        for f in os.listdir('/etc/pam.d'):
            print ("Rob says: " + f)
        content = f.read()

现在从这个临时目录再次运行升级程序，其中包括上面所做的编辑。像这样：

sudo /tmp/ubuntu-release-upgrader-l3yamuwr/DistUpgrade/jammy

答案2

您的 /etc/pam.d 目录中很可能有一个二进制文件。tar 或其他类似的软件包文件是导致此错误的常见原因。

答案3

unicode 解码错误并不重要。错误根源是 apt 或 dpkg 无法解决软件包依赖问题。软件包名称可以提示您无法解决的问题。请查看下面的 apt 错误消息行。

我自己也遇到了 libc:i386 依赖 libgcc-s1:i386 的问题。在一台不需要 i386 软件包或已标记安装 i386 arch 软件包的机器上。

删除残留物*_i386.deb，/var/cache/apt/archives让 dpkg 继续。您可能会遇到完全不同的依赖性问题。
