无法安装nvidia驱动程序-无法找到软件包

[更新] 我可以使用以下命令很好地安装375驱动程序

sudo apt-get install nvidia-375

但是下面的问题仍然存在381。[/ Update]

因此，昨晚我决定按照我在网上找到的一些步骤，将我的nvidia驱动程序更新为381。这是我遵循的步骤：

sudo apt-get purge nvidia*
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo apt-get install nvidia-381

每当我获得“ sudo apt-get install nvidia-381”命令时，我都会收到“无法找到软件包nvidia-381”

我到处搜索，找不到解决方案。有任何想法吗？

这是我的输出：

tyler@tyler-ubuntu:~$ sudo add-apt-repository ppa:graphics-drivers/ppa
 Fresh drivers from upstream, currently shipping Nvidia.

## What we're working on right now:

- Normal driver updates
- Help Wanted: Mesa Updates for Intel/AMD users, ping us if you want to help do this work, we're shorthanded.

## WARNINGS:

This PPA is currently in testing, you should be experienced with packaging before you dive in here:

Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/

### How you can help:

## Install PTS and benchmark your gear:

    sudo apt-get install phoronix-test-suite

Run the benchmark:

    phoronix-test-suite default-benchmark openarena xonotic tesseract gputest unigine-valley

and then say yes when it asks you to submit your results to openbechmarking.org. Then grab a cup of coffee, it takes a bit for the benchmarks to run. Depending on the version of Ubuntu you're using it might preferable for you to grabs PTS from upstream directly: http://www.phoronix-test-suite.com/?k=downloads

## Share your results with the community:

Post a link to your results (or any other feedback to): https://launchpad.net/~graphics-drivers-testers

Remember to rerun and resubmit the benchmarks after driver upgrades, this will allow us to gather a bunch of data on performance that we can share with everybody.

If you run into old documentation referring to other PPAs, you can help us by consolidating references to this PPA.

If someone wants to go ahead and start prototyping on `software-properties-gtk` on what the GUI should look like, please start hacking!

由于这是Google在该主题上排名最高的返回搜索，因此我想发布此信息，因为似乎情况已经改变。

这将不是一个新鲜的Ubuntu桌面18.0.4安装后为我工作：

sudo apt install nvidia-396

这将：

sudo apt install nvidia-driver-396

不知道为什么语法会更改。有关在网络上安装Nvidia驱动程序的大量信息，令人困惑。浪费了太多时间！

问题解决了。

在软件和更新>其他软件中验证我的PPA时，我注意到图形驱动程序PPA在PPA列表中列出了几次。我删除了所有与图形驱动程序有关的PPA，并从头开始安装，最后找到并安装了nvidia-381驱动程序。

我不确定为什么该存储库被列出了很多次，但是在删除并再次进行安装后，它终于可以正常工作了。

第二个命令是错误的。它应该是：

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt install nvidia-396

对于GeForce 8和9系列GPU使用 nvidia-340

对于GeForce 6和7系列GPU使用 nvidia-304

如果您查看ppa，则该程序包称为“ nvidia-graphics-drivers-381”

sudo apt-get install nvidia-graphics-drivers-381
