PowerShell Universal - 2026.1.0

I didn’t do much troubleshooting yet, but upgrading from 5.6.13 to 2026.1.0 caused all of my apps to fail to start. Errors indicating New-UDApp didn’t exist.

@AnonymousUser Feel free to open a support case is you don’t find the cause.

Will do! I do see that the Agent memory leak is fixed. Thanks for that!

I tried upgrading, from 5.6.13, didn’t work at all.

First indication something was wrong was that it asked me which account to use for the service, I gave it the credentials and continued.

Then it said my account had not permissions to install the service, and gave me no other choice than to abort the upgrade and rollback. After that everythiing works in 5.6.13 again.

This has never happened before for me, I’m used to keep the servers upgraded to the last version. So something has changed here.

This is on a server running Server 2025 Datacenter 24H2, using the msi installer.

We are tracking that issue here: MSI - Check if service exists with service account · Issue #3587 · ironmansoftware/powershell-universal · GitHub

It has been outstanding with v5 upgrades, but I do wonder if something with a major version bump is causing this to fail.

Sounds right, this was my first upgrade since completely reinstalling to get to 5.6. I don’t really get though, is there a way to get around it? I did input the credentials for the service account and still it said it couldn’t install the service because of permisson problems (unfortunately I didn’t write down the exact error).

You could try to unselect Start Service so that the installer doesn’t actually try to do that. Once the install has completed, go to services.msc, set the credentials for the service account and attempt the run the service.

The downside here is that the install won’t rollback automatically. The good thing is that while 2026.1 is a major upgrade in number, it’s not in going to cause any issue to go back to 5.6.13. You’d need to uninstall 2026.1 and then install 5.6.13.

I don’t know why the credentials didn’t work while entered in the installer itself. I’ve actually seen that in previous versions for some customers and the services.msc trick seems to work for them.

I don’t know why the credentials didn’t work while entered in the installer itself

Could it be a question of which format is used? I’m using a domain account but I only entered the username, maybe it should be username@domain or domain\username?

What is this new element about? All editors in the admin panel seem to have it.

I’ve never seen that. What browser are you using? Just a Chromium?

Tried this now. Unfortunately the service doesn’t start. I get the following in the event log, sounds like the problem is SQL permissions? Howerver the service account used to run PSU has the permissions in the database that it always had, it’s reader and writer.

edit: Don’t know if it’s relevant, but my connection string in appsettings.json looks like this:

“Server=[obfuscated server name];Database=PSU;Integrated Security=true;TrustServerCertificate=true;”

Yes, Chromium. A new browser profile has removed the element.

If you have some time, please email support. I’d like to schedule some time to look.

Just adding to the thread, I updated today (I use an automated method via the MSI), running as a service, none of the above issues seen for me & no other problems so far

Edit: I did see an issue which was breaking for one of my New-UDTables had to upgrade to 2026.1.1 to fix it.

none of the above issues seen

Wondering what could be the difference. I bet either it’s something to do with running the service using a domain account or authenticating against database using integrated logon.
I’ll file an issue tomorrow and include all my info there!

Can you share your automated process for updating?

I attempted updating and had the same issues dbytes and Dynamic are reporting. Didnt spend much time looking into it because our sever is used in production so Im back on 5.6.13 after uninstalling 2026.1 and reinstalling 5.6.13

we use the msi installer and run on windows server 2019 if it helps. Using Sqlite for the database

Essentially have a script that does the following.
Input parameter for the version number, defaults to “latest”
if latest, it gets it from:

$Version = (Invoke-WebRequest https://imsreleases.blob.core.windows.net/universal/production/v5-version.txt).Content

(Which is the same method as in the PSU module)

It then checks to see if the session is elevated, and throws if not.

it downloads the MSI:

Invoke-WebRequest "https://imsreleases.blob.core.windows.net/universal/production/$version/PowerShellUniversal.$Version.msi" -OutFile $Msi

Lastly I set the args for the installer, and use thread job to decouple the installer from the PSU job:

$InstallerArgs = "/I $Msi /q /norestart /L*V `"$Temp`PSU.msi.log.txt`""

    Import-Module "C:\Program Files\PowerShell\7\Modules\ThreadJob\ThreadJob.psd1" -ErrorAction Stop

    $Job = Start-ThreadJob -ScriptBlock {
        Stop-Service -Name "PowershellUniversal" -Confirm:$False
        Start-Sleep -Seconds 20
        Start-Process msiexec.exe -ArgumentList $Using:InstallerArgs -Wait -NoNewWindow
    }

That way it wont report back as a failure, or break anything in the current execution when it kills the service.

I’m on server 2019 too, sql DB tho, running the service with a domain joined service account

On my side, every Apps not running under the Integrated environment, I got the error indicating New-UDApp didn’t exist.

Can confirm Integrated works. Adam did send me reply that they found the issue and will be releasing an update soon.

I’m not sure who else is running their installations on Linux in Docker, but I’ve had issues upgrading with the following error:

I’ve even tried with a fresh installation and still get the same result. This is upgrading from ironmansoftware/universal:5.6.13-ubuntu-20.04 to devolutions/powershell-universal:2026.1.0-ubuntu-20.04. Even running devolutions/powershell-universal:2026.1.0-ubuntu-20.04 as a new installation without my data seems to have the same results. Every other version update I’ve done has been smooth sailing.

I found a solution to be able to use the “Powershell 7” environment.

Copy the folder “C:\Program Files (x86)\Universal\Modules\Devolutions.PowerShellUniversal” to “C:\Program Files (x86)\Universal\Hosts\7.5\Modules” and restart your App.

yep - the same - docker image is broken
