Hello,
I received an update for Abp.io, but after that update, many of its functions stopped working. When I create a new project, I get a 'Dbmigrator' error. Abp Studio won't open. Can you help me with this? Thank you.

- Solution
From your screenshots and description, there are two separate but related problems after the ABP Studio update:
- ABP Studio cannot open ABP Suite.
- The background task
DbMigratorfails when creating a new solution.
A very similar case was reported and solved; the root cause was a broken/global NuGet configuration on the machine, not ABP Studio itself.
ABP Studio (and its internal tools like
Volo.Abp.Studio.Cli, DbMigrator, ABP Suite) are installed and restored via dotnet / NuGet. If your globalNuGet.configpoints to an unreachable or invalid feed, these tools can’t be installed/restored, and you see generic “Couldn’t open ABP Suite” / “Job 'DbMigrator' FAILED” messages.Follow these steps:
1. Check and fix your global NuGet configuration
Locate your global
NuGet.configas explained in the official NuGet docs (usually under:- Windows:
%AppData%\NuGet\NuGet.config - macOS/Linux:
~/.config/NuGet/NuGet.configor~/.nuget/NuGet/NuGet.Config)
- Windows:
Open the file and look for
<packageSources>section.
If you see company‑internal or unreachable feeds (for example a URL that’s only valid on VPN or no longer exists), either:- Remove that
<add key="..." value="https://your-company-feed/..."/>line, or - Set
protocolVersion="3"and ensure the URL is correct and reachable, or - Temporarily disable it by setting
enabled="false"(on recent NuGet versions).
- Remove that
Ensure that at least
https://api.nuget.org/v3/index.jsonexists and is enabled as a source.Save the file.
This is exactly what solved the referenced case: removing a stale company NuGet source from
NuGet.configallowed ABP Studio to install its CLI/tools again.
2. Verify
Volo.Abp.Studio.Clican be installedOpen a terminal/command prompt and run:
dotnet tool install -g Volo.Abp.Studio.Clior, if it’s already installed:
dotnet tool update -g Volo.Abp.Studio.CliThese commands must complete successfully and download from
nuget.org.
If they still fail, the error message will usually point again to a NuGet feed issue; correct it as in step 1.
3. Restart ABP Studio and re-create a solution
- Close all running instances of ABP Studio.
- Start ABP Studio again.
- Create a new solution from the wizard.
- Watch the Background Tasks panel:
Checking pre-requirementsInstalling/using ABP Studio CLIJob 'DbMigrator'Opening ABP Suite
If your NuGet configuration is healthy, DbMigrator should complete and ABP Suite should open in a tab without the “Couldn’t open ABP Suite” dialog.
4. If problems persist – check the logs
If after fixing NuGet you still get failures:
Open the folder:
- Windows:
C:\Users\<YourUser>\.abp\studio\ui\logs - macOS/Linux:
/home/<user>/.abp/studio/ui/logs(or similar~/.abp/studio/ui/logs)
- Windows:
Open the latest log file and search for:
DbMigratorABP Suite.NET tool Volo.Abp.Studio.Cli installation failed
If you see errors referring to a specific NuGet source or network issue, you still have a NuGet configuration problem; correct the URLs or remove those sources and retry.
If the log shows a different error unrelated to NuGet (e.g., missing SDK, permission issue), address that message accordingly (install the referenced .NET SDK, fix permissions, etc.).

- I change NuGet.config
I ran the command dotnet tool update -g Volo.Abp.Studio.Cli, but nothing changed.
Then I removed ABP Studio from Windows Settings and reinstalled it, but the issue still remains.

When I create a new project, I get a 'Dbmigrator' error.
What happens when you run
*.DbMigratorproject manually? (if it is a non-layered template, you have to run the main project with--migrate-databasearg.)Abp Suite won't open.
Could you manually run it on console? Using the following command:
abp suite

I just tested now. There's no downloading problem happened on my side. A VPN connection or an anti-virus app can cause this. You can also log out from CLI and login again.
