PowerShell Universal - 2026.1.1

Errors don’t leak in the console anymore. Thanks for taking care of it so quickly.

Hi.

I actually succeeded in upgrading one of my environments now and starting the service. However none of my scripts are actually working in this version, it seems unable to load any PS modules. Calls to Import-Module just returns the following error:

The term ‘Import-PowerShellDataFile’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Any idea what this is about?

Updated my test box from 5.6.11 to 5.6.12 to 5.6.13 to 2026.1.1
Looks ok so far.

But shows that fragment in the app page editor.

Deleting cookies is no help.
But deleting the cache fixes it.

This might be relevant for everyone using CSP. I had to add “worker-src ‘self’ blob:;” and “data:” to “font-src ‘self’ https:;”
That resolves this issue and a few other console errors in the Admin UI:

I’ve upgraded our Azure container from 5.6.13 to 2026.1.1 but the container won’t start. It will give me an exit code 139.

Tried restarting the Azure App Service, even replaced the instance that was running the container.

We are running the container on a P1V3 instance (2 cores, 8gb mem).

Below is the log from the App Service that tries to start the container.

Anybody had the same issue? If so, how did you solve it?

Looks very similar to the bug from the last version. I think only Adam can fix it.

Make sure you pull 2026.1.1. Based on the log, it’s pulling 2026.1.0

Hi Adam,

thanks for the reply, completely missed the 2026.1.1 image, the 2026.1.0 image is still in the selection list on the docker hub.




But I now set the AppService to pull the 2026.1.1 image and it works again.

I only notice that there is an update warning about an image I can’t pull:

Is anyones defender kicking off at this release.

I installed the msi and got this:




I’m pretty sure this is a false positive however I need to explain this to internal it to avoid a device wipe.

This happens to me all the time in the first 1-2 days after a release.
I normally wait 3-4 days before updating so microsoft wont block the msi or any underlaying exe.

@Adam Driscoll I didn’t check this version yet, but if it has built in lasts devolutions powershell module, there is a bug with Get-DSEntries command that forcibly requires VaultID Input.

Already contact devolutions support and they report it as a bug and im waiting for a working version.

Working Version: 2025.2.3
Bug Version: 2025.3.3

@AnonymousUser We don’t package the Devolutions PowerShell module with PSU.

We’re looking at ways to alleviate this. The problem is that embedding the PS SDK looks risky to AV. One issue is that the server binary is not currently signed. We will be fixing that in an upcoming release in hopes that helps.

I’m having issues after upgrading from 5.6.13 to 2026.1.1. I created a new app and new script to confirm nothing in my code is the issue.

Get-PSUScript fails to return anything when run from the app. Log messages are below. Sample code is listed in the log message lines [2] and [3].

Additionally, connecting from vscode or a pwsh terminal using Connect-PSUServer returns the same error.

Get-PSUScript ‘Test_2026_1-1.ps1’

Get-PSUScript: Value cannot be null. (Parameter ‘value’)

They are already on it:

github.com/ironmansoftware/powershell-universal

Updated our dev server.
All went fine.

But now it tells me there is a new version 2026.1.1.0

And this fragment is back:



But CRTL-F5 in the browser fixes it.

I get the new version available as well.

I’m getting ‘Value cannot be null. (Parameter ‘value’)’ with get-psurole, get-psuidentity, I’m also showing that I have an upgrade available. but I just upgraded to 2026.1.1

I updated to 2026.1.1 only to fix the 2026.1.0 problems.. but now Get-PSUscript doesnt work, so my app that builds on generating forms from scripts is unfunctional. Please fix this asap

Is there any idea when 2026.1.2 is going to be released. I think I may need to revert my snapshot. This has broken critical API. The api calls both get-psurole and get-psuidentity - both of which return Value cannot be null. (Parameter ‘value’)

The root problem is already known, and Adam closed the issue right away, which makes me think it’s going to be ready in a few days. However, if it’s critical, I would roll back the snapshot and not take the risk in case the problem takes more time than expected.

An update, I reverted to 5.6.13 and all works well

Updated to 2026.1.1 and New-UDUpload seems to not be working anymore, nothing happens when pressing the button

I think versions 2026.1.1 and 2026.1.0 should be removed from the CDN, as they contain breaking changes. With all due respect. @Adam Driscoll

Calls to Import-Module just returns the following error:
The term ‘Import-PowerShellDataFile’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Just for the record: Tried 2026.1.2 and this problem mysteriously has vanished, even though I don’t see anything in the changelog about it. So now I got one environment that’s upgraded!
