Unable to start VirtualBox VM on Ubuntu – Kernel driver not installed

I’m fairly new to Ubuntu and would like to learn more in a safer environment than using my host machine. I’m running Ubuntu 18.04 Kernel 5.3.1 and am struggling to create a VirtualBox Ubuntu VM.

When I try to start the machine I get:


Running modprobe xboxdrv as root I get:

modprobe xboxdrv modprobe: FATAL: Module xboxdrv not found in directory /lib/modules/5.3.1-050301-generic 

When I run:

sudo apt install --reinstall virtualbox-dkms 

Unpacking virtualbox-dkms (5.2.32-dfsg-0~ubuntu18.04.1) over (5.2.32-dfsg-0~ubuntu18.04.1) … Setting up virtualbox-dkms (5.2.32-dfsg-0~ubuntu18.04.1) … Loading new virtualbox-5.2.32 DKMS files… Building for 5.3.1-050301-generic Building initial module for 5.3.1-050301-generic ERROR (dkms apport): kernel package linux-headers-5.3.1-050301-generic is not supported Error!

How do I get VirtualBox running on Ubuntu?

Unable to locate package libapache2-mod-php7.0

I’m trying to install Rainloop Webmail on Debian.

I’ve added the next package

add-apt-repository ppa:ondrej/php 

This key was added: 4F4EA0AAE5267A6C

But upon apt-get update: Reading package lists... Done    E: The repository 'http://ppa.launchpad.net/ondrej/php/ubuntu eoan Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. 

All solutions that I find are removing the repository, but how can I install the libapache2-mod-php7.0 package then?


Showing unable to locate libmysql-java after sudo apt-get install libmysql-java statement

Even I have tried java-mysql but also showing this Reading package lists… Done Building dependency tree
Reading state information… Done E: Unable to locate package java-mysql

I have Just downloaded the package and now I don’t know where to place it.

Unable to execute PHP, throws 500 error. Able to upload and execute all others

I need some serious help. I managed to upload a PHP shell using an upload form with some tweaking. No such restrictions except it renames the uploaded file to md5.But when I tried to execute the shell, It shows a 500 error. I am able to view or download all other files such as HTML, JS, JPG etc. On digging further, i found that there is a HTACCESS file with the content below. Is there a possibility that php is not executing because of the permissions? Is there a way to execute php or gain shell using any other ways?

Options -Indexes  <files .htaccess>   order allow,deny   deny from all </files>  #Add all file you want to protect... <FilesMatch "\.(htaccess|htpasswd|ini|zip|rar|mp3|phps|fla|psd|log|sh|php)$  ">   Order Allow,Deny   Deny from all </FilesMatch> 

Unable to install Ubuntu server LTS via USB drive

Errors received shown above. I’m not exactly sure what they mean or if they can actually be fixed (is a hardware problem a real possibility?) So far I have:

  1. Reset CMOS
  2. Tried every USB port on my mobo
  3. Reinstalled iso on thumbdrive multiple times
  4. Disabled USB 3.0 in BIOS
  5. Installed ubuntu on a different computer and moved the drive to this one. This did work and ubuntu technically ran but there were other errors that I couldn’t seem to fix (for starters eth0 wouldn’t show up)

Potential solution (that I will try tomorrow):

After further research, it seems that there is a quirk with Gigabyte motherboards. I will use a 4gb partition and enable IOMMU as highlighted here: Dual Boot Ubuntu 14.04 with Windows 7 on UEFI

If this solution fixes my issue I’ll delete this question tomorrow.

Completely unable to uninstall broken nvidia drivers :( [19.04 – KDE]

During an update, my nvidia drivers were completely broken and I’ve been unable to uninstall the broken ones and reinstall new ones. GPU is the Quadro K2100M (GK106GLM). Ubuntu version is 19.04 Machine is the Dell Precision M4800.

when I run ” sudo apt –purge autoremove nvidia* ” I get this ( https://i.imgur.com/oLGTWxn.jpg )

When I run “apt –fix-broken install” I get this ( https://i.imgur.com/OP1bmbD.jpg )

lsmod | grep nvidia returns this ( https://i.imgur.com/4YODZCx.jpg )

sudo ubuntu-drivers autoinstall returns this ( https://i.imgur.com/IA65W18.jpg )

I’m at a loss, all tutorials I can find online referring to how to remove broken nvidia drivers doesn’t seem to be effective. Can anyone help? apt-autoremove hasn’t helped either 🙁 I have tried downloading the .run installer from nvidia’s site to no avil, claiming it cannot build the kernel module.

Thanks to the broken packages, I cannot apt install, apt remove, apt dist-upgrade, or anything of that sort :/

Edit: “sudo apt clean” and “sudo apt autoclean” have not helped

Unable to achieve SharePoint Looping/Parallel Workflow – Designer 2013

I have been trying to complete a workflow all week to NO AVAIL. I’ve used loops, parallel blocks, ect. You name it, I’ve tried it. I am losing my mind, any help is appreciated.

My requirements are as follows:

  1. send out an initial assignment email with a due date
  2. If the item’s status is ‘in process’ (which is it by default) loop/wait for the reminder date to equal the current date and then send out a reminder email.
  3. Once the reminder email is sent, wait for the item to be completed and then send out a completion email notification.
  4. If the item’s status changes from ‘in process’ to ‘complete’ BEFORE the reminder email is due to be sent, exit the loop/wait and send a completion email out WITHOUT sending a reminder email out.

my latest attempt:
