解决：（Ubuntu 22.04.5 LTS 系统）

修改源配置，终端输入以下内容

# 创建正确的 ARM64 架构软件源配置 sudo tee /etc/apt/sources.list << 'EOF' # Ubuntu 22.04 LTS (jammy) for ARM64 - 清华镜像 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-security main restricted universe multiverse # 或者使用官方源（如果清华镜像有问题） # deb http://ports.ubuntu.com/ubuntu-ports/ jammy main restricted universe multiverse # deb http://ports.ubuntu.com/ubuntu-ports/ jammy-updates main restricted universe multiverse # deb http://ports.ubuntu.com/ubuntu-ports/ jammy-backports main restricted universe multiverse # deb http://ports.ubuntu.com/ubuntu-ports/ jammy-security main restricted universe multiverse EOF

# 1. 应用上面的正确配置 # （直接复制上面 sudo tee 开头的整个代码块到终端执行） # 2. 清理并更新 sudo apt clean sudo rm -rf /var/lib/apt/lists/* sudo apt update # 3. 验证架构 echo "检查仓库架构..." apt policy | grep -A2 "packages from" # 4. 现在安装Qt6 sudo apt install qt6-base-dev
