问题 Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 months ago . Improve this question Yesterday I reinstalled my Ubuntu (for unrelated reasons) and since then ssh behaves very weirdly. It takes suuuper long to connect (multiple minutes).

Ubuntu - PySide module not found for python2 but works fine for python3

由 房东的猫 提交于 2021-02-05 08:22:26
问题 I had PyQt4 running fine with python2 on Ubuntu 12.04. I then installed python-PySide. But the installation test would give me a module not found error. Then I installed python3-PySide and it works fine. So obviously something to do with my environment paths, but I'm not sure what I need to do. I'm guessing PySide is automatically checking if python3 exists and if it does then it'll use it regardless. I need PySide to work with python2.7 because of Qt4.8 compatibility issues. Any suggestions?

microk8s + ingress: ingressed service always resolves to 127.0.0.1 and not pod ip

问题 I am learning about microk8s and how ingress works. I have a single node microk8s (v1.18.4) with the following add-ons: DNS, ingress, RBAC, storage I am trying to get it working with the microbot example. I've read (and reread) through the tutorial but, the address, once the ingress manifest is applied results with the microbot service, routed to 127.0.0.1 (and not the internal pod IP). I am attempting to access the app: http://192.168.91.166/microbot via web external to the vm that it's

[TOC] Ubuntu Kylin（中文又被称为优麒麟）是基于Ubuntu的一款官方衍生版。它是一款专门为中国市场打造的免费操作系统。它包括Ubuntu用户期待的各种功能，并配有必备的中文软件及程序。 下载镜像 安装 虚拟机安装 1.打开虚拟机， 这里是VMware12，新建虚拟机，我是选择典型安装，下一步。 2.安装来源：选择稍后安装操作系统，如果这个时候选择了镜像，VMware 将会帮你简易安装，为了更详细配置，这里选择稍后，然后点击下一步； 3.客户机操作系统：当然是选择linux，版本是Ubantu64位，点击下一步 4.虚拟机名称：默认，也可以自己顺便写。位置：推荐存储在非系统盘 C 盘，虚拟机需要占大量的空间，所以存在非系统盘，防止日后系统盘空间不足； 5.设定磁盘大小，这里看个人需求吧，我这里给比较多，下一步 6.点击自定义硬件去设置 设置好内存，设置为 4G ，然后设置 2核处理器 ；网络适配器选择 桥接 选择使用ISO映像文件，选择你下载的镜像文件，其他选项就默认吧，点击关闭 ###系统安装 7.开启虚拟机准备安装，选择中文简体，安装Ubuntu 8.然后我选择了安装第三方软件，也可以不选 你喜欢，点击继续 9.因为我这虚拟机没安装其他系统，所以选第一项安装了 10.其他默认继续； 12.这个就是Ubuntu的主界。 结束！！！！！！！！！！！ vmware
