“由于公钥不可用，无法验证以下签名”

我想更新我的 22.04 系统上的软件包，但不幸的是我收到了这个错误：

sudo apt-get update

Err:5 https://apt.repos.intel.com/oneapi all InRelease   
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY BAC6F0C353D04109 
Fetched 4,451 B in 0s (9,069 B/s) 
Reading package lists... Done 
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. 
GPG error: https://apt.repos.intel.com/oneapi all InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY BAC6F0C353D04109 
W: Failed to fetch https://apt.repos.intel.com/oneapi/dists/all/InRelease  
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY BAC6F0C353D04109 
W: Some index files failed to download. They have been ignored, or old ones used instead.

为什么会这样/解决方案是什么？

我尝试了这个但是没有用：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys BAC6F0C353D04109

我实际上并不使用有问题的包（以防卸载是最简单的方法）。

请假设我知道的很少。

出错的存储库为英特尔的 Linux OneAPI 工具包提供服务，它为 AI、物联网、HPC（高性能计算）等提供开发人员工具。与任何添加到系统中的存储库一样，也需要添加签名（即 GPG/pgp）。我遇到了和你一模一样的问题，我认为签名可能已过期，需要更新。

我重复了步骤 3 的两个说明https://www.intel.com/content/www/us/en/docs/oneapi/installation-guide-linux/2023-0/apt.html页：

# download the key to system keyring
wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg > /dev/null

# add signed entry to apt sources and configure the APT client to use Intel repository:
echo "deb [signed-by=/usr/share/keyrings/oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list

之后apt update我的系统上没有出现任何错误。升级这些软件包可能需要 11GB 以上的可用空间，所以请记住这一点！
