Chocolatey v2.4.3
Chocolatey detected you are not running from an elevated command shell
 (cmd/powershell).

 You may experience errors - many functions/packages
 require admin rights. Only advanced users should run choco w/out an
 elevated shell. When you open the command shell, you should ensure
 that you do so with "Run as Administrator" selected. If you are
 attempting to use Chocolatey in a non-administrator setting, you
 must select a different location other than the default install
 location. See
 https://docs.chocolatey.org/en-us/choco/setup#non-administrative-install
 for details.

This may mean that a different user or administrator is holding this lock and that this process does not have permission to access it. If no other process is currently performing an operation on this file it may mean that an earlier NuGet process crashed and left an inaccessible lock file, in this case removing the file 'C:\ProgramData\chocolatey\lib\db0e682efc626efbeefc5047db74030bbb94838e' will allow NuGet to continue.
