networks: installing kubernetes on Ubuntu 16.04 and 19.10 eliminates network connectivity

Following these steps to install kubernetes in Ubuntu 19.10 running on VMWare player with bridged networking. Installing kubernetes destroys the network connectivity of my guest OS. Specifically, it is this command that kills my network connectivity:

sudo apt-get install kubeadm kubelet kubectl -y

To regain my network connectivity, I had to remove all three packets and then remove two network interfaces:

sudo ip link del flannel.1
sudo ip link del cni0

I don't know why the flannel was there because I hadn't installed it yet. Maybe it was leftover from a previous attempt where I installed flannel and the removal failed.

I noticed the same problem in Ubuntu 16.04 that runs natively, so this is probably not a VMWare Player issue. I was able to install kubeadm, kubelet and kubectl on Ubuntu 18.04 running natively with no problems. I need another node though.

Kubernetes is supposed to run on Ubuntu 16.04+. Are the installation steps different for 16.04 and 19.10? It seems strange that I kill my network.

dual boot: I click the + button to create a partition while installing xubuntu but nothing happens

I have a laptop and I already have Windows 10 installed. I like having xubuntu (dual boot mode) installed. I downloaded the xubuntu × 64 iso and created a bootable usb. I also have around 50G of unlocated space on my hard drive. When I click the + button (to create boot, swap, and root partitions) it doesn't work. I have been waiting about 1 hour hoping this will work, but I did not.

networks: problems installing nginx in VirtualBox VM

I am running Ubuntu Server 18.04.4 on a VM VirtualBox on Windows 8.1.

I am trying to install nginx. I have followed these steps:

  1. Set up port forwarding in VirtualBox:

VirtualBox port forwarding image

  1. sudo apt install nginx

  2. sudo ufw allow "Nginx Full"

Now I point my browser to http://127.0.0.1:8000 and look … nothing. Time is not running out, please load an empty page. I was hoping to see the nginx welcome page. Where am I going wrong?

Is installing the app and disk usage only 0.3%?

I am a computer enthusiast. I was installing Visual Studio on my Windows machine and I noticed that the disk usage only reached 20% and the same for the CPU. I was wondering why the operating system doesn't use more resources to finish the installation process sooner.

Installing MS Office Fonts on Windows Server

There are a lot of fonts installed with MS Office that are not present in Windows Server 2019. We have a web application, part of its functionality is to convert Office documents to PDF. When these documents contain fonts that are not present on the server, the resulting PDF is not processed as it should. The solution is to ensure that the MS Office fonts are installed on the server.

I know how to install fonts, is to get the fonts and get full list of Office fonts missing in Windows Server 2019, that's the problem.

Is there an easy way to install the fonts that come with MS Office on Windows Server without having to install Office itself?

Is there a MS Office font pack available?

Is the only easy solution here to install Office on the server?

Don't try to avoid buying a copy from the licensed office. Try to avoid unnecessary installation of applications that are not necessary on the server and that can affect the security of the system.

python: installing seaborn and scipy on Windows 10

I have a conda environment with Python 3.7 on Windows 10. Conda is version 4.5.11. It has the pip version 20.0.2. I want to run born and scipy libraries in Python. Following the tips here, I downloaded .whl files from here that match my version of Python and my 64-bit architecture. pip install in these libraries it was successful, and the libraries are listed in my environment. But when I try to import them:

import seaborn
import scipy
import pylab

I get a DLL loading error.

Getting some basic Python packages to work on Windows 10 is a mess.

web hosting: I can no longer download files from the web space after installing WordPress

over the weekend I installed WordPress on my web space to create a new home page. Everything works fine so far.

Everything? Not all. I noticed that I can no longer download any files from my web space. The home page itself works fine.

I read about the _.htaccess file. The file was in my webspace before, so I reloaded the old file, but it still doesn't work.

I just want to allow download zip files and I want to be able to access the file apple-app-site-association. This is an important file for one of my applications.

How can i fix this? I tried to delete the _.htaccess file, but it still doesn't work.

Any help is appreciated.

hard drive: RAM and HDD disappear from Windows after installing new NVME SSD

I have a really strange problem.

I just installed a new PCIe NVME M.2 SSD and after booting into Windows 2 of my old HDD are not visible even in Device Manager.

I have Gigabyte B450 AORUS M, 3x SATA HDD, 1 SATA system SSD and now the new NVME disk, WIN 10. So the system now only sees SATA SSD, NVME SSD and 1 out of 3 SATA HDD.

And in addition to that, Windows now only sees 8 GB of memory, I mean in Control Panel System and Security System it says: Installed memory: 16 GB (8 GB usable). So this RAM is there, it just can't be used for any reason.

What's up with that? I checked the hard drive and memory cables, but everything seems fine. I just turned off my PC, removed the GPU to access the M.2 slot, put the GPU back in and turned it back on.

nvidia – Is the HP laptop getting too hot after installing Ubuntu?

I have a pretty decent laptop and it should be more than enough to run Ubuntu for programming, but Ubuntu seems to be much hotter than it should be, compared to Windows 10. I'm new to Linux and I use Ubuntu 18.0.4

I have an HP EliteBook 8570w. CPU: Intel® Core i7-3630QM RAM: 8GB DDR3 GPU: NVIDIA Quadro K1000M

Any suggestion?
