我已经尝试过下面这个。
按 Ctrl+Alt+T 打开终端。
输入命令 sudo nano /etc/apt/sources.list 。在此文件中，搜索 vivaldi 存储库。
现在，将该行替换为：
deb [信任=是]https://repo.vivaldi.com/archive/deb/stable main 现在，按 Ctrl+X，然后按 y，然后按 Enter 保存文件。
最后，更新包列表：
sudo apt 更新
但我明白了

答案1
repo.vivaldi.com 的当前 Vivaldi 网站证书已于 2020 年 1 月 2 日到期，因此您无法再使用 https 连接它。
这不是您的系统故障。
这是 Vivaldi 网站的问题。只有他们能修复它。请随时告知 Vivaldi 人员其网站存在的问题。
