Upgrade steps

Reference: https://ubuntu.com/server/docs/how-to-upgrade-your-release

1. 進行升版

   ​​​​sudo do-release-upgrade
   

2. 詢問是否繼續時停下，仔細看是否有無問題，尤其注意更新後是否會造成系統不正常
   可按下 d 來看 detail
   

   • 注意套件是否有對應 version，尤其是 No candidate ver: xxx 的套件是否正常
     • CUDA
     • Nvidia driver
     • 等等

3. 遇到 version conflict 時，請一律都用 D 檢查更動部分，如無問題，則以 maintainer version 為主
   

4. 如被詢問 unattended-upgrades 設定，請選擇 No
   

5. 升級完後 reboot

Post-upgrade steps

Outline

• 更新 apt repo version

CUDA

1. 刪除舊的 CUDA apt repo (20.04)
   ​​​​sudo rm /etc/apt/sources.list.d/cuda-ubuntu2004-x86_64.list*
   

2. 重新下載安裝 CUDA apt repo (22.04)
   ​​​​wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
   
   ​​​​sudo dpkg -i cuda-keyring_1.1-1_all.deb
   

3. 更新 CUDA keyring
   ​​​​sudo apt update
   ​​​​# (如果需要)
   ​​​​sudo apt upgrade
   

Docker engine (二擇一執行)

Official (recommended)

重新執行 Docker 第一項安裝步驟，將 apt repo 覆蓋，from focal to jammy

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

Manual

將 focal 取代成 jammy

# 確認是否正確
sed 's/focal/jammy/g' /etc/apt/sources.list.d/docker.list

# 直接取代
sed -i 's/focal/jammy/g' /etc/apt/sources.list.d/docker.list

Git-LFS (二擇一執行)

Official (recommended)

重新執行 Git-LFS 安裝步驟，將 apt repo 覆蓋，from focal to jammy
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash

Manual

將 focal 取代成 jammy

# 確認是否正確
sed 's/focal/jammy/g' /etc/apt/sources.list.d/github_git-lfs.list

# 直接取代
sed -i 's/focal/jammy/g' /etc/apt/sources.list.d/github_git-lfs.list

停止 Unattended-Upgrades 套件

sudo systemctl disable --now unattended-upgrades
sudo nano /etc/apt/apt.conf.d/20auto-upgrades

# 把這行 APT::Periodic::Unattended-Upgrade "1"; 改成 "0"
