MinGW pacman -Sys Unable to lock database

To start Code and Compile C++, must install a compiler. For my case, it is MSYS2 through which MinGW is available. According to the installation guild mentioned on the website, I installed the software without any errors. Now I was supposed to update the package database and base packages by entering pacman -Sys but it has shown an error error: failed to synchronize all databases (unable to lock database)

After searching online for a solution I found that deleting/removing the db.lck will work, for that, I used this command rm /var/lib/pacman/db.lck but it showed another error. Right now there is no solution to this on the internet. I've also pasted the terminal output of MSYS2 MSYS for refernce.

$ pacman -Sys
:: Synchronizing package databases...
error: failed to synchronize all databases (unable to lock database)

VIRAT@DESKTOP-97BS0AB MSYS ~
$ rm /var/lib/pacman/db.lck
rm: cannot remove '/var/lib/pacman/db.lck': No such file or directory

As I found there 2 solutions for this error. Try both :

Solution : 1

  1. C:\Users\your_account_name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\MSYS2 64bit

  2. Run "MSYS2 MSYS" as administrator

  3. Run the command : pacman -Syu

Solution - 2 :

  1. C:\msys64\var\lib\pacman ( Go to the downloaded folder)

  2. Delete the "db.lck" file
