尝试删除 nvidia-304 包时出现“UnicodeDecodeError：'utf-8'编解码器无法解码位置 0 中的字节 0xff：无效的起始字节”错误

我正在尝试nvidia-304从我的系统（Ubuntu 14.04）中删除软件包，但收到此错误：

我想删除它，因为

  1. 它没有被使用
  2. fslint由于nvidia-304软件包未完全配置，尝试安装失败

所有问题都是从版本 13.10 升级到 14.04 LTS 后才开始出现的。

我该如何解决这个问题？

答案1

确切的错误在这里：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

您无法从中间代码的意义上修复它并修复它。是一个漏洞从开发人员的角度来看，IMO 很容易修复（修改文件的编码）。现在，删除包的唯一方法是强行，我不建议在任何情况下这样做。

我发现这/usr/share/ubuntu-drivers-common/quirks/put_your_quirks_here似乎是一个虚拟文件，并且可能是问题的原因。file /usr/share/ubuntu-drivers-common/quirks/*当文件不是 UTF-8 时，您应该检查一下，如下所示：

$ file /mnt/usr/share/ubuntu-drivers-common/quirks/*
/mnt/usr/share/ubuntu-drivers-common/quirks/dell_latitude:        ASCII text
/mnt/usr/share/ubuntu-drivers-common/quirks/lenovo_thinkpad:      ASCII text
/mnt/usr/share/ubuntu-drivers-common/quirks/put_your_quirks_here: empty

如果这些文件不是ASCII text，请考虑将它们全部删除，然后再次尝试删除该包。
