简单记录安装 ubuntu 后常用的命令，当个备份。

常用命令

1. 升级系统

   sudo apt update
   sudo apt upgrade

2. 安装软件

   sudo apt install vim cmake build-essential htop neofetch axel git chromium-browser

3. 禁用自动更新

   sudo vim /etc/apt/apt.conf.d/10periodic
   sudo vim /etc/apt/apt.conf.d/20auto-upgrades
   sudo systemctl disable apt-daily.timer
   sudo systemctl disable apt-daily-upgrade.timer
   sudo apt purge update-notifier*

4. 卸载 firefox

   sudo snap remove firefox

5. 安装 nvidia 驱动

   查看显卡驱动版本

   sudo ubuntu-drivers list

   安装指定版本

   sudo ubuntu-drivers install nvidia:545

6. 安装 conda

   浏览器访问：https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/, 下载新版，bash 运行即可

   pip 换源

   pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

   conda 换源

   conda config --set show_channel_urls yes
   vim ~/.condarc

   添加如下内容：

   channels:
     - defaults
   show_channel_urls: true
   default_channels:
     - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
     - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
     - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
   custom_channels:
     conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
     msys2: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
     bioconda: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

7. 配置自启服务 (参考模板)

   [Unit]
   Description=jupyter
   After=network.target
    
   [Service]
   Type=simple
   Restart=on-failure
   RestartSec=5s
   ExecStart=/home/acai/miniconda3/bin/jupyter-lab 
   WorkingDirectory=/home/acai  
   
   User=acai
    
   [Install]
   WantedBy=multi-user.target
