每当我将 wget 用于以下或通常的任何事情时，
sudo wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
我收到一条错误信息:

这导致了更广泛的连接问题，但这是最常见和最直接的问题，我似乎找不到太多支持。使用 Ubuntu 20.04 并且实际上只是在 3 小时前对我的计算机进行了重新镜像(可能与此有关...)
通过运行 wget -d cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.17.2.tar.xz 编辑附加信息:

附加信息/usr/bin/wget 是路径:

ii wget 1.20.3-1ubuntu1 amd64 retrieves files from the web
最佳答案
当您尝试访问的网站没有有效的 SSL 证书时，会弹出此错误。如果是这种情况，除非您拥有该远程网站，否则您将无法使用他们的 ssl 解决他们的问题。
因此 wget 的建议:使用 --no-check-certificate 参数，这样 wget 就不会在连接时尝试验证 SSL。
如果您的错误是:Unable to locally verify the issuer's authority，那么您应该确保您的服务器/计算机 TIME 是正确的。
关于ubuntu - 每当我使用 wget 时出现证书错误消息，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61419286/
