The newstore source is down, which breaks the client entirely unless you add --source winget to all of your commands. I made a bug about this a few weeks ago: https://github.com/microsoft/winget-cli/issues/1349.

BTW, for anyone at MS troubleshooting, it’s the manifestSearch endpoint throwing 500s:

@adrianghc you can winget source remove newstore. It still gets a “tombstone” so it shouldn’t show back up unless you disable/reenable the experimental store and then do a winget source reset --force from an elevated prompt.

I have same issue + I can’t download apps from microsoft store too

With --source winget it works perfectly, many thanks.

I just turned on my machine and also got this error…

Yeah, no problem.

You can also run winget source reset to have the client attempt resolving source related issues and add “default” sources back.

@Jaifroid can you share the output from winget source list and winget features?

Here you go:

PS C:\Users\gkant> winget source list
Name     Argument
------------------------------------------------------
winget   https://winget.azureedge.net/cache
newstore https://storeedgefd.dsx.mp.microsoft.com/v9.0
PS C:\Users\gkant> winget features
The following experimental features are in progress.
They can be configured through the settings file 'winget settings'.

Feature                 Status   Property            Link
-----------------------------------------------------------------------------------
Microsoft Store Support Disabled experimentalMSStore https://aka.ms/winget-settings
Packaged API Support    Enabled  packagedAPI         https://aka.ms/winget-settings

Thanks for the data points! It looks like we may have another release coming for the experimental store source in the next day or two. It was not built with the reference implementation, so we’re working through some design decisions and legacy systems.

For a bit more transparency, the engineering team working on the store source is working through some technical limitations on how some of the search criteria works. The current implementation is tightly coupled with the search UI in the Microsoft Store. This is likely to have a very long lead time (many months) to get where we want it to be for command-line scenarios supporting the Windows Package Manager.

@denelon Can you reopen this? It’s the only issue noting that the source is down.

Edit: I just remembered that it’s Labor Day, so the team is probably off. Uh, @Fukubi, can you do it?

I think you need to add -t Microsoft.Rest.

winget source add -t Microsoft.Rest -n newstore https://storeedgefd.dsx.mp.microsoft.com/v9.0 worked for me.

Also works for me. Thanks!

I think you need to add -t Microsoft.Rest.

winget source add -t Microsoft.Rest -n newstore https://storeedgefd.dsx.mp.microsoft.com/v9.0 worked for me.

Can confirm that it worked. But imho, it’s surprising that this was necessary. ‘winget source list’ doesn’t mention “Type” anywhere. So it’s far from obvious that this flag needs to be added. Especially since the error code didn’t mention it either.

I think you need to add -t Microsoft.Rest.

winget source add -t Microsoft.Rest -n newstore https://storeedgefd.dsx.mp.microsoft.com/v9.0 worked for me.

+1 this started working for me this morning as well. Thanks to whoever brought it back to life! Having to remember --source winget was a drag 😃

@denelon I don’t have any updates in the MS Store, maybe it’s because I’m using the preview version?

Here’s the version details that you asked

And about the internal server error, I still have it

[winget list]
Ocorreu um erro inesperado ao executar o comando:
0x801901f4 : Erro interno de servidor (500).

I’m currently also having the issue. My Microsoft Store version is 22109.1401.3.0 (there aren’t any updates available).

I am facing same issue, as mentioned above for now --source winget seems to work

I have the same issue as well, frustrating.
