使用sudp apt update && sudo apt upgrade命令一直提示错误

Reading package lists… Done

W: https://download.docker.com/linux/ubuntu/dists/kinetic/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

E: The repository ‘https://mirrors.ustc.edu.cn/ubuntu kinetic Release’ does not have a Release file.

N: Updating from such a repository can’t be done securely, and is therefore disabled by default.

 

1. 清除APT缓存和旧的GPG密钥：运行以下命令清除APT软件包列表的缓存信息和旧的GPG密钥：

sudo rm -rf /var/lib/apt/lists/*

sudo rm /etc/apt/trusted.gpg

2. 更新软件源信息：确保/etc/apt/sources.list中仅包含官方源的信息，然后运行以下命令更新软件源列表：

sudo apt update

3. 更新GPG密钥：您可能需要添加Docker软件源的新GPG密钥，如果您仍然想从Docker官方源安装软件。您可以使用以下命令添加Docker的GPG密钥：

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg –dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

 

接着，更新apt配置以使用新的密钥：

echo “deb [arch=$(dpkg –print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable” | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4. 再次运行sudo apt update来重新更新软件源列表。
