Unable to resolve package source
When trying to install a module via Powershell on a new machine, I was getting the following error:
PS C:\Users\Administrator> Find-Module AzureRM
WARNING: Unable to resolve package source 'https://www.powershellgallery.com/api/v2'.

+ FullyQualifiedErrorId : NoMatchFoundForCriteria,Microsoft.PowerShell.PackageManagement.Cmdlets.FindPackageThis issue occurs when PowerShell tries to connect to the PowerShell Gallery repository using legacy TLS/SSL protocols instead of the current TLS 1.2 or the newer TLS 1.3.
The resolution
We need to make sure we force powershell to be using TLS 1.2 due to the deprication of TLS 1.0, the destination that hosts the module wont accept a TLS 1.0 connection.
To fix it, run an elevated PowerShell prompt as usual. This will force your PowerShell to use TLS 1.2 rather than TLS 1.0.
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12Now you can see if the package is available from the gallery with the Find-Module command, and now when trying to reinstall you should no longer get the error.
PS C:\> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
