当我分配这台服务器时，它有两个版本的 python（2.7 和 3.6），然后我必须手动安装 3.10，因为我想要使用的 Netbox 版本至少需要 3.8。
一切看起来都很好，直到我意识到walinuxagent（Azure Linux 代理）不起作用。似乎 Python 有问题。
Azure Linux 代理
- 我已经
apt remove --purge walinuxagent通过以下方式重新安装apt install walinuxagent但仍然不起作用：
$ sudo systemctl status walinuxagent.service

有人知道如何解决这个问题吗？
更新 1：情况有所改善
我卸载了 Python 3.10.9，删除了符号链接并替换为操作系统原有的 python 版本，然后重新配置update-alternatives了python和python3。

walinuxagent运行良好。

问题是我需要将 pythoin 3.6 升级到 python 3.8、3.9、3.10 或 3.11，而不会弄乱一切
更新 2：新问题
我设法安装python 3.6了python 3.10，问题是当3.6在更新替代方案中选择了 ，则walinuxagent服务在 时工作正常netbox，netbox-rq而 则nginx服务不工作；相反的情况发生在3.10已选定。
一种解决方法是根据要启动的服务选择每个 Python 版本。有没有办法避免每次都这样做？
答案1
可能已经太晚了，但我通过更改服务配置以使用 python 版本 3.6 解决了这个问题。
sudo nano /lib/systemd/system/walinuxagent.service
#Change python3 by pnone-reload
sudo systemctl restart walinuxagent
#and check that the service is working
sudo systemctl status walinuxagent
