Ubuntu 22.04.3下执行apt update时VSCodium仓库证书验证失败的问题求助

最近在完全更新后的Ubuntu 22.04.3上执行sudo apt update时，碰到了VSCodium仓库的证书验证失败问题，具体错误信息如下：

Err:7 https://download.vscodium.com/debs vscodium InRelease
Certificate verification failed: The certificate is NOT trusted. The name in the certificate does not match the expected. Could not handshake: Error in the certificate verification. [IP: 138.199.36.10 443]
W: Failed to fetch https://download.vscodium.com/debs/dists/vscodium/InRelease Certificate verification failed: The certificate is NOT trusted. The name in the certificate does not match the expected. Could not handshake: Error in the certificate verification. [IP: 138.199.36.10 443]
W: Some index files failed to download. They have been ignored, or old ones used instead.

针对这个问题，你可以尝试以下几个步骤来修复：

• 移除旧的VSCodium仓库配置和密钥，避免旧配置干扰：
  依次执行以下命令：

  sudo rm /etc/apt/sources.list.d/vscodium.list
  sudo rm /usr/share/keyrings/vscodium-archive-keyring.gpg
  

• 重新添加官方的VSCodium GPG密钥：
  执行这条命令来获取并安装最新的验证密钥：

  wget -qO - https://gitlab.com/paulcarroty/vscodium-deb-rpm-repo/raw/master/pub.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/vscodium-archive-keyring.gpg > /dev/null
  

• 添加正确的VSCodium仓库源：
  把官方仓库源写入系统配置文件：

  echo 'deb [ signed-by=/usr/share/keyrings/vscodium-archive-keyring.gpg ] https://download.vscodium.com/debs vscodium main' | sudo tee /etc/apt/sources.list.d/vscodium.list
  

• 再次执行更新命令：
  现在重新运行更新，应该就能正常获取VSCodium的仓库索引了：

  sudo apt update
  

如果以上步骤还没解决问题，可以检查一下这两个点：

1. 系统时间是否正确：证书验证依赖准确的系统时间，执行sudo timedatectl set-ntp true可以同步网络时间；
2. 是否有代理或防火墙干扰：如果使用了代理，确保代理配置正确，不会拦截HTTPS请求的证书验证。
