无法更新 Ubuntu 18.04

我有Ubuntu 18.04和蟒蛇3.7。

uname -a
Linux username-laptop 4.15.0-109-generic #110-Ubuntu SMP Tue Jun 23 02:39:32 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

当我运行时sudo apt-get update出现此错误：

E: The repository 'http://dl.bintray.com/aluxian/deb stable Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

我试过这解决方案，但我也无法打开软件和更新。

我终于可以自己解决问题了。在此之前，我这样做了，sudo update-alternatives --config python3并改用python 3.6 python 版本变化 之后，我按照同一篇文章的答案（之前我无法这样做，因为软件和更新无法打开）并取消勾选https://dl.bintray.com/aluxian/deb。 然后sudo apt-get update问题就解决了！
