Flame_Phoenix's questions

Background

I have a Windows 10 machine with a SSD where I have installed Ubuntu LTS 20.04. This setup worked wonderfully for months. When I turn my machine on I get to choose which operative system to use.

Problem

That is, until yesterday. Yesterday I logged on my Windows boot, did nothing special and then turned the machine off. Windows probably installed some updates after I left.

Today I turned my machine on and realized I couldn't log on to my Ubuntu partition, where all of my work is:

Failed to open \EFI\BOOT\grubx64.efi - Not Found  
Failed to load image \EFI\BOOT\grubx64.efi: Not Found    
start_image() returned Not Found  

Research

I did some searching around but it looks like this problem has a specific solution for each case.

So I installed Boot-repair, and got the following diagnostics link:

https://paste.ubuntu.com/p/TdbRzdmQsZ/

I didn't run the "Recommended Repair" option yet, as this was discouraged in a similar problem in favor of asking advice to the community first:

Error: "Failed to open \EFI\BOOT\grubx64.efi..." (Dual-Booting)

Questions

My Ubuntu partition is where all of my work is. I cannot stress the importance of this dual boot working properly. With this in mind I have the following questions:

• How can I fix the issue now?
• How can I prevent it from ever happening again?

Background

I have a small script that changes my wallpaper to a random image:

#!/bin/bash
feh --randomize --bg-fill /home/USERNAME/Pictures/wallpapers/*

It works like a charm, so I decided to add it to the startup applications, like in this question:

• how to run a specific command via a bash script and add in to a startup

Problem

Everything works fine except for one problem:

• On start up, the wallpaper is changed via the script, as expected. Then, seconds after, Ubuntu takes over and replaces that wallpaper with the default one.

Question

How can I keep this from happening?

Backgound

I am trying to run an sh script every minute using crontab, but it is not working.

Problem

When I run the script manually, it executes properly, however crontab can't do it.

I created the job using crontab -e, and I can see cron is running because if I type pgrep cron I get the PID in return.

I also know that my time format is correct because I tested it with this online tester.

Code

wallpaperSlider.sh:

#!/bin/bash
feh --randomize --bg-fill /home/username/Pictures/wallpapers/*

crontab job:

SHELL=/bin/bash

* * * * * username /home/username/.crons/wallpaperSlider.sh

Research

I have read the most common errors in AskUbuntu and I don't think I am experiencing any.

I understand that perhaps I am missing some environment variable, but I am not sure how to check that.

I also know that crontab -e changes/creates a tmp file, in my case /tmp/crontab.wCajAu/crontab.

Question

1. How can I make this script execute in cron?
2. Having in mind that crontab -e changes a file in the tmp folder, will I lose all changes once I reboot?

Problem

I am trying to get rid of mongodb-org-server once and for all, but this is rather challenging. No matter what I do, I always end up with the same errors:

(Reading database ... 74764 files and directories currently installed.)

To solve this, I tried following another solution:

• Can not uninstall MongoDB

but to no avail.

Questions

Any solutions? At this point I am considering a complete format ....

I need to read metadata from one of my movies in mp4 format and to do that I need a very basic mp4 (for movies) metadata editor. Which programs can you recommend ? (Since I don't know any).

I don't need media organizers, nor anything fancy, just something that allows me to peek inside the file.

I am trying to compile a program using maven in my Linux 12.04. In order to do, I use the mvn clean install command. However I get a build error:

[ERROR] Unable to locate the Javac Compiler in:
  /usr/lib/jvm/java-6-openjdk-amd64/jre/../lib/tools.jar
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
In most cases you can change the location of your Java
installation by setting the JAVA_HOME environment variable.

I check the path and indeed I am missing that critical file. This is what I have:

So apparently, I am running openJDK, but I am missing files. How do I fix this?

I am running Ubuntu 12.04 LTS.

I have downloaded several programs (Eclipse, Sublime Text Editor, SmartGit) and they all come in ZIP format. Once I uncompress them I can use them, but I cannot access them via the Dash Home Menu, like I explain in this thread:

• How do I install 3rd party programs and make them appear in the Dash Home menu?

In that thread the answer was in creating a XXX.desktop file, populate it with random fields, and then move that file to a specific folder.

I now want to do the same for my Eclipe and SmartGit programs (as well as to any other programs I may end up using) so now I believe I need to learn how to create an XXX.desktop file with the correct fields and the correct instructions.

Where can I find the information to do that?

I just downloaded Sublime Text Editor, and I unpacked the tarball. However, now I want to make it searchable in the Dash Board menu, like all applications that are installed using the Ubuntu Software Center. How do I do it?

I am trying to install Spark IM in my fresh install of Ubuntu 12.04, however I am running into all kinds of problems. The steps I have taken so far were:

1. Download the tar.gz file from the website
2. Unpack it into my Desktop
3. sudo mv Desktop/Spark/ /opt/

Then I try to run the file as root sudo sh /opt/Spark/Spark, but I get the following error:

/opt/Spark/Spark: 150: /opt/Spark/Spark: bin/unpack200: not found
Error unpacking jar files. Aborting.
You might need administrative priviledges for this operation.

Since I was running the file as root (using admin) I do not understand why it says that "might need" administrative privileges ...

Here is the output of running ls -Al:

The file I am trying to run is a "sh" file, so I do not need to do sudo chmod +x Spark right?

Why is this not running? What do I need to do to fix it?

I have my Windows partition (C), 9GB of free space and then I have my Linux partition. How do I expand my Linux partition with that 9GB of free space using Gparted and without losing everything I have?

If this is not possible, is there another tool (safer one) that I can use?

I am trying to install Spark IM in my Ubuntun VM, however I am running into all kinds of problems. The steps I have taken so far were:

1. Download the tar.gz file from the website
2. Unpack it
3. cd /home/user/Downloads/Spark
4. sudo chmod +x Spark
5. sudo chmod +x starter
6. cd ..
7. sudo mv Spark/ /opt

To run, the Spark IM, I do the following commands:

1. sudo su
2. cd /opt
3. sh Spark/Spark

And as a result, I get the error:

Preparing JRE ...
Spark/Spark: 150: Spark/Spark: bin/unpack200: Permission denied
Error unpacking jar files. Aborting.
You might need administrative priviledges for this operation.

Which makes no sense at all, because I am running in root mode. If I run sh Spark/starter I get the exact same mistake. If I try to run it as an executable file, I get a similar error:

bash: ./Spark/starter: Permission denied

What am I doing wrong? Why can I not install this?

I am trying to enable Intel VT-x on my Clevo W150ER. The processor is an Intel i7-3610QM and it supports Intel VT-x. However, I've read that my motherboard also has to support it, namely, the chipsets of the motherboard must support it. So I was wondering if anyone here knows a command that can tell me which chipsets my motherboard is using and if they support Intel VT-x as well.
