意外拒绝使用 apt 安装 nvidia-cudnn 许可证，现在我无法卸载它

我尝试安装 nvidia-cudnn，但速度有点快，提示也有点乱。我在尝试安装时不小心按了拒绝。现在，当我尝试卸载时，出现以下错误：

$ sudo apt purge nvidia-cudnn -y
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following packages will be REMOVED
  nvidia-cudnn*
0 to upgrade, 0 to newly install, 1 to remove and 3 not to upgrade.
After this operation, 45.1 kB disk space will be freed.

dpkg: too many errors, stopping
Errors were encountered while processing:
 nvidia-cudnn
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)

手动删除sudo rm -r /usr/share/doc/nvidia-cudnn然后sudo rm /var/lib/dpkg/info/nvidia-cudnn*似乎sudo apt purge nvidia-cudnn不起作用。当我尝试再次安装时，不再提示我输入许可证。我尝试在“卸载”和重新安装之间重新启动。许可证接受/拒绝信息保存在哪里？我如何强制它再次提示我输入许可证？

在发生混乱之前和之后我都使用此命令来安装 cudnnsudo apt install nvidia-cudnn

现在我得到的是：

$ sudo apt install nvidia-cudnn

卸载过程失败，因为预删除脚本 ( /var/lib/dpkg/info/nvidia-cudnn.prerm) 返回非零退出状态。在内部，预删除脚本调用 update-nvidia-cudnn -p位于/usr/sbin/update-nvidia-cudnn 第 164 行之后的 ( echo Purging cuDNN installation from ${PREFIX}) 运行的命令purge_cudnn ${PREFIX}失败。

我能够通过强制exit 0从文件第 164 行后update-nvidia-cudnn -p添加来解决这个问题。exit 0/usr/sbin/update-nvidia-cudnn

综上所述，将文件末尾编辑/usr/sbin/update-nvidia-cudnn为：

...
elif test "${DO_PURGE}" -ne 0; then
    echo Purging cuDNN installation from ${PREFIX}
    exit 0  # added
    purge_cudnn ${PREFIX}
fi

卸载过程即可完成。然后如果nvidia-cudnn再次安装，安装程序将再次要求您同意许可证。

要删除已安装的应用程序，正确的方法是执行安装的反向命令。

安装 nvidia-cudnn

这是您用于安装的命令。因此，删除应用程序的命令将是。

sudo apt 删除 nvidia-cudnn

强行移除不是一个好主意，而且可能会留下一些残渣。
