Loki Wallet 3.0.2 & 2.0.2 Crashing in Windows 10

How to update and fix the issue above

For weeks I have been fighting with the Loki wallet on my Windows 10 VM. I even went out and built a fresh laptop with a fresh install of Windows 10, only to have LOKI crash once I put in my password.

If you are experiencing these issues too, you are not alone.

To fix this issue, I had completely wiped LOKI off of my computer. Searched the C: drive for *loki* and wiped everything. The only reason I could do this is because I had my keys backed up along with my personal seed. IF YOUR KEYS AND SEED ARE NOT BACKED UP, DO NOT DELETE ANYTHING!

So, with a fresh computer, free of loki, I downloaded the new GUI wallet from:

https://github.com/loki-project/loki-electron-gui-wallet/releases

Once the app is downloaded, install it as usual and then launch the app.

On the first time it runs, you will want to set it up to download the blockchain locally. Do not select the remote options. Then you will want to input your wallet seed. Make sure you backup the keys. Setup your wallet password, and let it sync with the blockchain. You will FINALLY see a working version of LOKI! Finally!

I am not sure what ruined their Festive Freya or Summer Sigyn, but thankfully that bug doesn’t affect their Electron wallet.

TeamViewer 14 Login Issue on Ubuntu 18.04.01

How-To Remove TeamViewer 14 From Ubuntu 18.04

Ubuntu Server 16.04.05 USB Installation Requesting CD-ROM

How to fix the Insert CD-ROM Notification when you are not installing from CD-ROM

This fix is simple.  You are running the Ubuntu server installation from a USB drive. 

You get the dialog box asking for the CD-ROM…Simply remove the USB drive (that has the installation media on it) from the port that it is plugged into. 

Move it to another USB Port….and the installation will find the device, think it is a CD-ROM and the install will continue.

Installing Teamviewer 13 on Ubuntu 18.04

How to Install Teamviewer on a Headless Server

Teamviewer Installation has changed in the recent version, and the prior directions will not work.  You will continue to receive an error after you insert the password saying there was a connectivity time out.  The new way to install teamviewer is as follows:

Login 

sudo bash

add-apt-repository “deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe”

apt-get update

apt-get install gdebi-core

mkdir /home/miner/teamviewer

cd /home/miner/teamviewer

wget https://download.teamviewer.com/download/linux/teamviewer-host_amd64.deb

dpkg -i teamviewer-host_amd64.deb

It will fail and that’s ok because we will fix it here

apt-get -f install

y

After it installs then type

teamviewer info

Take a note of your Teamviewer ID, you will need it later

teamviewer passwd YOURPASSWORDHERE

Now open teamviewer on another computer that you are logged into.  Add the computer using the menu “Add Computer“, enter in your Teamviewer ID and the Password you used in YOURPASSWORDHERE, and you can now connect
