安装 NVIDIA 驱动程序 - “sudo ubuntu-drivers autoinstall”出现 UnboundLocalError？

导游对于我正在使用的 60 分钟旧版 Ubuntu 22.04 系统，它会告诉我是否同意运行的建议sudo ubuntu-drivers autoinstall。但这给了我一个错误。

peter@peter-NBINF-O5-12R5N-54:~$ sudo ubuntu-drivers autoinstall

    with_nvidia_kms = version >= 470
UnboundLocalError: local variable 'version' referenced before assignment

如果我使用以下命令打开该文件，我可以看到完整的功能nano：

def nvidia_desktop_pre_installation_hook(to_install):
    '''Applies changes that need to happen before installing the NVIDIA drivers'''
    with_nvidia_kms = False

    # Enable KMS if nvidia >= 470
    for package_name in to_install:
        if package_name.startswith('nvidia-driver-'):
            try:
                version = int(package_name.split('-')[-1])
            except ValueError:
                pass
            finally:
                with_nvidia_kms = version >= 470

    if with_nvidia_kms:
        set_nvidia_kms(1)

我应该怎么办？

答案1

下一行导游已经基本上说明了如何解决自动安装程序的问题：

# Use the 'recommended' driver from the output of the earlier step, running `ubuntu-drivers devices`
sudo apt install nvidia-driver-530-open

所以这基本上是 PEBCAK（虽然我不明白为什么自动安装程序脚本将来不能对 NVIDIA KMS 做出更好的猜测，无论它是什么，或者正确解析带有 -server 或 -open 后缀的 nvidia-driver 字符串，也许通过获取拆分字符串的第 [2] 个元素而不是最后一个元素，也许将来会这样做）。

为了补充背景信息，我之前的步骤如下：
