今天apt-get update的时候报错。说winHQ的key无效。
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 818A435C5FCBF54A
后来在 http://ubuntuhandbook.org/index.php/2018/09/how-to-install-wine-stable-3-0-3-in-ubuntu-18-04/ 找到答案，需要安装新的key:
Did you successfully install the repository key?
Download the key via command:
wget -nc https://dl.winehq.org/wine-builds/Release.key
Then install the downloaded key file:
sudo apt-key add Release.key
然后apt-get update后问题解除。
这样我可以继续安装我的nodejs14.
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
