我可以在 Ubuntu 20.04 上安装 Python 3.10apt而不用担心它会破坏 Python 3.8 吗？
我在许多项目中使用 Python 3.8。
我会运行这个：
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.10
编辑：
仅使用 Python 3.10 virtualenv。
我正在尝试检查 SMART 数据。我已经Ubuntu 18.04安装在Kingston A1000, M.2 - 480GBSSD上。
我可以检查所有其他磁盘，但这个。
milano@milano-PC:~$ sudo hdparm -I /dev/nvme0n1p1
/dev/nvme0n1p1:
HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device
你知道怎么检查吗？
尝试安装可以正常运行的YouTube To MP3应用程序。Ubuntu 18.04Ubuntu 16.04
当我双击该deb文件时，它会运行GUI安装程序，但是当我单击 时install，它会开始安装，然后停止并没有显示任何错误，但install按钮仍然存在。
所以我尝试手动安装它，但也有错误。我将在这里向您展示我的步骤：
milano@milano-PC:~/Downloads$ sudo dpkg -i youtube-to-mp3-converter3-9-4-64-bit.deb

所以问题是它没有安装依赖项：
milano@milano-PC:~/Downloads$ sudo apt-get install libqt4-declarative

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libqt4-declarative : Depends: libqt4-network (= 4:4.8.7+dfsg-7ubuntu1) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
所以我这样做：

然后，当我再次尝试安装该应用程序时，第一步又发生了。

你知道该怎么做吗？
编辑

Package libav-tools is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
ffmpeg:i386 ffmpeg
E: Package 'libav-tools' has no installation candidate
最近，我注意到我的电脑很慢（甚至 youtube 视频也不流畅）。
我有acer aspire nitro 5，我的电池可能没电了。
我认为它是由于 CPU 温度高而节流，但事实并非如此：
传感器
我可以看到 CPU 频率约为 800.000 MHZ，这是可能的最低频率。
处理器
如您所见，使用率非常高（我启动了 Intellij Idea）
[
我试图手动将 CPU 频率设置为最大值：
sudo cpufreq-set -f `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq`
但它返回错误：
设置新值时出错。常见错误： - 您是否拥有适当的管理权限？（超级用户？） - 您请求的调速器是否可用并已修改？- 试图设置无效的政策？- 尝试设置特定频率，但用户空间调控器不可用，例如因为硬件无法设置为特定频率或用户空间调控器未加载？
你知道我该怎么做吗？
我有一些关于 DigitalOcean VPS 的项目。我经常部署部分代码。几乎每次上传后，我都必须执行多个命令。
例如，如果我更改 Django 模型并添加一些静态文件：
我必须通过 ssh 连接并且：
activate virtualenv
cd to /home/django/project/
python manage.py makemigrations
python manage.py migrate
python manage.py collectstatic
sudo systemctl daemon-reload
sudo systemctl restart gunicorn
sudo systemctl restart nginx
sudo supervisorctl
restart celery_worker
当然，我不需要每次都使用所有命令。
我想让使用这些命令更舒服。
是否有一些应用程序可以定义这些命令，然后从中选择并执行？
我想到的最接近的事情是创建 shell 脚本，但也许有更好的选择。
我使用PyCharm进行部署。我检查了文档，但没有找到这样的功能，但也许有。
