Repair Corrupt VirtualBox .vbox File

Error in VirtualBox VBOX

These are the steps that VirtualBox takes when it writes a new Vbox file. Each step is contingent on the last one being completed without errors.

  • Write a temporary file with ".vbox-tmp" extension.
  • Delete any existing ".vbox-prev" file.
  • Rename existing ".vbox" file to ".vbox-prev".
  • Rename ".vbox-tmp" to ".vbox".

Have not tried these yet

The error that comes after the corruption of the vbox XML file is usually caused when the system locks up; thus preventing the virtualization software from finalizing the writing out to its file of configuration. The error probably implies that the <VirtualBox> opening tag on the line 2 of the file did not have any corresponding </VirtualBox> closing tag at the file’s end.

The fastest method of finding out if this is exactly what has caused the problem in your case; you can locate your vbox XML file for the Guest Operating System, whose home directory location is inside the folder of ‘VirtualBox’ in the ‘Machines’ folder in the ‘Name-of-Your-Guest-OS-Directory’ folder, saved as ‘Name-of-Your-Guest-OS.xml file’

The cause of the problem and the emergence of the error message could probably be simply that the XML file was badly corrupted whose repair process is easy and quick and might take only a minute to be repaired.

  • Open the .vbox XML file in a text editor
  • Then, go to that file’s last line
  • On not seeing any closing tag of </VirtualBox>, it is confirmed that your XML file is corrupt.
  • Now, initiate by adding this closing tag at the end of the file
  • And then, from there, try and work your way back.
  • Look through the file for the <Opening Tags> which do not have any needed </Closing Tag>
  • Another way is to use some XML validation service
  • Just after a few rounds of the three easy steps of Copying -> Pasting -> Validating, you can successfully repair corrupt vbox XML file.

Delete Empty Directories

Refer: https://unix.stackexchange.com/questions/46322/how-can-i-recursively-delete-empty-directories-in-my-home-directory

The find command is the primary tool for recursive file system operations. Use the -type d expression to tell find you're interested in finding directories only (and not plain files).
The GNU version of find supports the -empty test, so

Print all empty directories below your current directory.
find . -type d -empty -print

After you've verified that this is selecting the correct directories, use -delete to delete all matches:
find . -type d -empty -delete

Issues with Virtual Box – File Not Found

Refer: https://forums.virtualbox.org/viewtopic.php?f=6&t=75068

These are the steps that VirtualBox takes when it writes a new Vbox file. Each step is contingent on the last one being completed without errors.

  • Make a backup of the temporary file with ".vbox-tmp" extension.
  • Delete any existing ".vbox-prev" file or change it to -BAK001 extension
  • Rename existing ".vbox" file to ".vbox-prev".
  • Rename ".vbox-tmp" to ".vbox"

Refer: https://www.techprevue.com/virtualbox-inaccessible-file-not-found/

iii) Out of the above-mentioned issues, "File not found" is the most common one. During that situation, you can go to the location of the file. One of the possibilities is that you might find suffixes after the extension .xml for eg. .xmlmog or .xmlemf. So if you are looking for file abcd.xml it actually exists there by name abcd.xmlemf and hence your system was unable to find the file abcd.xml because it did not exist. Now what you can do is, simply copy the file and paste it in the same location and rename it with extension just .xml. This would solve the issue of an inaccessible "file not found" error.

Installing Wine 5.0 on Ubuntu 18.04

Refer: https://itsfoss.com/wine-5-release/

Troubleshooting

Things worked much better when changing the compatibility to Windows XP.  Navigate to each *.exe and add compatibility to Windows XP.  Have done this for Dreamweaver, Fireworks, TN3270, WinSCP and Textpad

How to install Wine 5.0 on Ubuntu and Linux Mint

If you have Wine installed before, you should remove it completely to avoid any conflict (as you wish). Also, the WineHQ key repository key was changed recently, you should refer to its download page for additional instructions on that according to your Linux distribution.

The source for Wine 5.0 is available on its official website. You can read more about building wine in order to make it work. Arch-based users should be getting it soon.

Here’ I’ll show you the steps to install Wine 5.0 on Ubuntu and other Ubuntu-based distributions.

First, remove existing Wine install with this command:

sudo apt remove winehq-stable wine-stable wine1.6

Download the official Wine repository key and add it:

wget -qO - https://dl.winehq.org/wine-builds/winehq.key | sudo apt-key add -

Now the next step involves adding the repository and for that, you need to know your Ubuntu version first.

For Ubuntu 19.10, add this repository:

sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ eoan main'

If you are using Ubuntu 18.04 or Linux Mint 19.x, use this command to add the repository:

sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'

For Ubuntu 16.04 and Linux Mint 18.x series, you can use this command:

sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'

Now that you have added the correct repository, you can install Wine 5.0 using this command:

sudo apt update && sudo apt install --install-recommends winehq-stable

Swan – Better Linux on Windows

Refer: https://hackaday.com/2017/03/29/swan-better-linux-on-windows/

Install WSL on Window: https://docs.microsoft.com/en-us/windows/wsl/install-win10

Open and Run the Following PowerShell Command as Administrator:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Download your Distribution of Choice and then you need to initialize it from the start menu.

Background of Swan, I'm using MobXterm.

If you are a Linux user that has to use Windows — or even a Windows user that needs some Linux support — Cygwin has long been a great tool for getting things done. It provides a nearly complete Linux toolset. It also provides almost the entire Linux API, so that anything it doesn’t supply can probably be built from source. You can even write code on Windows, compile and test it and (usually) port it over to Linux painlessly.

However, Cygwin’s package management is a little clunky and setting up the GUI environment has always been tricky, especially for new users. A project called Swan aims to make a full-featured X11 Linux environment easy to install on Windows.

The project uses Cygwin along with Xfce for its desktop. Cygwin provides pretty good Windows integration, but Swan also includes extra features. For example, you can make your default browser the Windows browser with a single click. It also includes spm — a package manager for Cygwin that is somewhat easier to use, although it still launches the default package manager to do the work (this isn’t a new idea, by the way).
