Fix VirtualBox (copy/move/restore) VM

If you have moved a VM or have an old copy of working VM, you can land in situation where the VirtualBox software is reinstalled or moved and you get errors when you restore old VMs or move some.

Could not find an open hard disk with UUID {2219b9d1-8931-418c-a7d5-d5ce00c81b7c}.
Result Code:


Virtual Box UUID {17c3.........} does not match the value {3c1b...} 
stored in the media registry ('/home/user/.VirtualBox/VirtualBox.xml')
Machine UUID {899a89219ax-7d55-8381-01ac-288288101} doesn't match its UUID {0388cb75-f076-4992-ab96-ed8d2ff99623} in the registry file
Result code: NS_ERROR_FAILURE (0x80004005}

The solution I found is based on the answers here:

https://stackoverflow.com/questions/15074878/virtual-box-uuid-07c3-does-not-match-the-value-2c1b-stored-in-th and my experience.

First – check if you have running the VirtualBox with the right user! Sometimes errors can occur if you have installed the VirtualBox with different user and the current one is not admin or does not have enough rights!!!

Second – fix the UUID like below.

Copy existing VM (duplicate) via VirtualBox to create a new folder and working VM.

Rename the VirtualBox.vdi file to VirtualBox0.vdi of the new VM.

Get the UUID of the working VM with the following command:

The result should look like:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands dumphdinfo VirtualBox0.vdi
--- Dumping VD Disk, Images=1
Dumping VD image "polikont_feb2016-disk1.vdi" (Backend=VDI)
Dumping VDI image "polikont_feb2016-disk1.vdi" mode=r/o uOpenFlags=9 File=0x0002586d731290
Header: Version=00010001 Type=1 Flags=0 Size=85888373760
Header: cbBlock=1048576 cbBlockExtra=0 cBlocks=81910 cBlocksAllocated=13687
Header: offBlocks=512 offData=328192
Header: Geometry: C/H/S=1024/255/63 cbSector=512
Header: uuidCreation={0388cb75-f076-4992-ab96-ed8d2ff99623}
Header: uuidModification={24bde4bc-e7cf-4d60-8f40-a257b3460228}

Set UUID to the restored/copied VM which was giving error (I have renamed it to VirtualBox.vdi in the directory of the working copy, after I have renamed the working VDI to VirtualBox0.vdi and taken its UUID as shown above). So set its UUID as follow:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands sethduuid  VirtualBox.vdi 0388cb75-f076-4992-ab96-ed8d2ff99623

Replace the UUID (0388cb75-f076-4992-ab96-ed8d2ff99623) with your result from dumphdinfo command!

*** This was experienced and tested in VirtualBox 7.0 under Windows 10 at May 2024.

Google Drive API v3 (googleapiclient.errors.HttpError 404 File not found)

If you try to upload a file in a shared drive (in Google Drive) you may get the above error.

This is my experience and solution as of February 2024 using Python 3.10.

from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload
from google.oauth2 import service_account

from io import BytesIO
from googleapiclient.http import MediaIoBaseUpload
from google.cloud import translate_v2 as translate

## Credentials of service account
credentials = service_account.Credentials.from_service_account_info(service_account_info, scopes=['https://www.googleapis.com/auth/drive'])

## API Client Service
service = build("drive", "v3", credentials=credentials)

# buffer_memory=BytesIO(b"some initial binary data: \x00\x01") # BytesIO() new_body
buffer_memory=BytesIO() # BytesIO() new_body

## Prepare the file in memory (you can upload local file too with MediaBase Upload)
media_body = MediaIoBaseUpload(buffer_memory, mimetype='text/html', 
        chunksize=1024*1024, resumable=False)
                body = {
                        'title': file_name,
                        "name": file_name,
                        "mimeType": "application/vnd.google-apps.document",
                        "driveId": "0APee............PVA",
                        "parents": ['0APe.............PVA'],

## Upload file
returned_fields="id, name, mimeType, size, webViewLink, exportLinks"
upload_response=service.files().create( body=body,                                                            

## Share the created file with user
user_permission = {
                    "type": "user",
                    "role": "writer",
                    "emailAddress": share_user,
                perm_response = service.permissions().create(

The important difference between uploading in private Google drive is that you have to use the following parameters for Shared Drives:

driveId -> Id of Shared Drive
parents -> Folder or Shared Drive

Mime Types: List of the supported Mime type here


If you want to convert the uploaded file to Google Drive native format use the following parameter:

"mimeType": "application/vnd.google-apps.document",

Google documentation: https://developers.google.com/drive/api/guides/manage-uploads

And this article on StackOverflow as well helped to find the solution although some parameters are wrong or deprecated already: https://stackoverflow.com/questions/67622131/google-drive-api-v3-googleapiclient-errors-httperror-404-file-not-found

iPhone battery replacement / смяна на батерия на Айфон

Верни на традицията си Apple са поставили поредната пръчка в лесните и безпроблемни ремонти и поддръжка на телефоните си.

Последното е след като се смени батерията да покзва грешка в менюто с Настройки и да не се виждат различни детайли както за оригиналната батерия.

Иначе добър клип как се сменя батерия на iPhone SE 2020 е този, защото показва как хитро да изтеглиш залепващата лента с навиване.
В другите клипове просто дърпат – това работи докато е нова лентата и телефона. При телефон на 2+ години просто се къса:

Chrome browser: Bypass “Your connection is not private” Message

Interesting post on how to bypass the Chrome browser “Your connection is not private” and other SSL errors.

What I learned and I liked is Option 2:

Option 2 – Prevent Warning

  1. Click a blank section of the denial page.
  2. Using your keyboard, type thisisunsafe and press Enter. This will add the website to a safe list, where you should not be prompted again.

It surely works!
