sudo do-release-upgrade -cd

返回

Checking for a new Ubuntu release
New release '22.04' available.
Run 'do-release-upgrade' to upgrade to it.

然后

sudo do-release-upgrade

返回

Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.

我认为错误是：

22.04 未标记为 LTS。因此do-release-upgrade不适用于从 20.04 LTS 升级到 22.04 LTS。

任何解决方法除了set Prompt=normal in /etc/update-manager/release-upgrades.？

最近我在运行时注意到一些问题apt，系统会警告我密钥环已弃用：

这不会阻止我执行更新，但我更希望在更新系统时看不到这一点。我们应该如何存储受信任的 GPG 密钥？

我正在运行 Ubuntu 20.04，我不小心删除了 EFI 分区（该死的 GParted！）系统仍在运行。我可以在 now UNUSED 区域创建一个新分区，设置 EFI 标志和引导标志，然后运行 ​​update-grub 吗？update-grub 会重新填充 EFI 分区吗？我可以从另一个 Ubuntu 安装中 DD EFI 分区吗？

快速回复， 非常感谢！

已经使用 Ubuntu 18.04 几年了，并且读到 Python 2 已从 Ubuntu 20.04 中删除，我期待使用命令pythonorpip而不是python3or pip3。所以今天我第一次尝试了Ubuntu 20.04，发现：

$ python --version

Command 'python' not found

$ python3 --version
Python 3.8.5

我很惊讶，在进一步调查后发现了以下关于包裹的信息python-is-python3：

https://packages.ubuntu.com/focal/python-is-python3

https://launchpad.net/ubuntu/focal/+package/python-is-python3

如何使“python”程序命令执行 Python 3？

这 3 个链接的中间是最具描述性的，但没有一个特别清楚如果要在 Ubuntu 20.04 安装上运行是什么python-is-python3/做什么以及后果的全部范围。sudo apt-get install python-is-python3

以下是我的一些问题python-is-python3：

  1. 是python-is-python3Ubuntu/Canonical 专有的吗？如果是这样，其他 Linux 发行版python-is-python3是否也使用或其他一些发行版是否有类似的等价物？

  2. 我收集如果我python-is-python3要从命令提示符运行，那么我可以使用命令python而不是python3. 首先有人可以确认这一点，其次，是否也适用于pip，即pip代替pip3?

  3. 上面的 launchpad.net 链接提到了符号链接的创建。python-is-python3真的只是创建一个符号链接吗？为这样一个简单的目的引入一个包似乎很奇怪。此外，如果此软件包随后被卸载（i.e. sudo apt --purge remove python-is-python3），这是否会删除符号链接？

  4. 现在还有常用的 Python 2 包吗？我想不出任何临时的。

  5. 有没有人因为事先没有意识到的原因而跑了python-is-python3，后来又后悔了？

  6. 似乎运行的好处python-is-python3是不必在 Python 命令的末尾添加 3，但缺点是你会有一个非标准的 Ubuntu 设置，这是对python-is-python3优点/缺点的公平总结吗？

Power...Settings... 中的以下项目指出：

可以关闭Wi-Fi以节省电量

wifi可以关掉

您可以看到该选项当前已打开。这应该意味着允许系统关闭 Wi-Fi 以节省电量。

但是，当我关闭该选项时，我的 Wi-Fi 被禁用（关闭）。

我试图告诉系统不允许关闭 Wi-Fi 以节省电量。

但是，当我关闭该选项时，它实际上会关闭 Wi-Fi。电源...设置中似乎没有正确描述此项目。

注意：这个选项在 Ubuntu 18.04 下也是一样的。

在新的 ubuntu 20.10 虚拟机上为本地存储库设置密钥，我收到一条消息，提示 apt-key add 已弃用，我应该阅读apt-key(8) 手册页。( apt-key8) 手册页是串在一起的单词的集合，但如果它包含信息，我就无法将其剔除。谁能告诉我，我应该在终端上输入什么，而不是：

apt-key add name-of-file

在向我鸣喇叭后，该命令显然仍然有效，所以我能够继续，但想知道我将来需要做什么。
