sudo apt-add存储库multiverse拒绝错误连接。

Question

我试图根据i386将蒸汽令指令源代码添加到64位Linux中。但是，我得到了以下错误：

user@mintpc:/home/steam/games/steamapps$ sudo apt-add-repository multiverse
No protocol specified
Unable to init server: Could not connect: Connection refused
No protocol specified
Unable to init server: Could not connect: Connection refused

我不知道这意味着什么，互联网上似乎也没有答案。

不幸的是，我没有任何答案给您，但我要补充的是，在我的Linux框中添加python 3.10的死蛇回购时，我遇到了同样的问题：

sudo add-apt-repository ppa:deadsnakes/ppa
Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused
Cannot add PPA: '"Failed to download the PPA: HTTPSConnectionPool(host='launchpad.net', port=443): Max retries exceeded with url: /api/1.0/~deadsnakes/+archive/ppa (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f9d3e72a340>: Failed to establish a new connection: [Errno 101] Network is unreachable'))."'.

我刚刚运行了一个完整的系统更新，下载并安装了几十个软件包，如果我运行.

sudo nping --tcp -p 443 ppa.launchpad.net

...I得到回复，所以我有点不知所措，无法解释发生了什么。
