Running UI-Path 2019.04 process in Studio 2020.10.2

Help Studio

Hi,
we recently installed new dev systems with studio 20.10.2.
When we load Processes created with studio 2019.04 some package dependencies are broken: e.g. (other packages have the same issue)
NU1103: Unable to find a stable package Microsoft.Bcl.AsyncInterfaces with version (>= 1.1.1)

  • Found 1 version(s) in C:\Program Files (x86)\UiPath\Studio.\Packages [ Nearest version: 5.0.0-rc.1.20451.14 ]
  • Found 1 version(s) in Local [ Nearest version: 5.0.0-rc.1.20451.14 ]
  • Found 0 version(s) in /nuget/activities
  • Found 0 version(s) in https://gallery.uipath.com/api/v2
  • Found 0 version(s) in Connect
  • Found 0 version(s) in https://www.myget.org/F/workflow/
  • Found 0 version(s) in Official

When i start to update the dependencies vai “Manage Packages”, the update fail: “Package installation failure”
What s wrong? or where can i get more information what is failing here?
Thanks
mti

Hi @mti,
Welcome to the Community!
Some of the packages are changed a lot since mentioned version. By change I mean the core code of them is completely different and it makes same activity unavailable to apply the setup you may had for them before. It means that for some steps / automations you need to make re-design.

Thanks Pablito,
of cause there might be some steps, which could make trouble.
But what is the issue that we cannot update any package?
Cheers

In your case I see this package Microsoft.Bcl.AsyncInterfaces which seems to be not any package available by official UiPath feed. It seems to be something added by you. If it comes from any external feed then you need to use same feed for Orchestrator.

ok, this is a error message from a very simple process:
NU1102: Unable to find package UiPath.System.Activities with version (= 20.10.3)

  • Found 2 version(s) in /orchestrator/nuget/activities [ Nearest version: 19.10.1 ]
  • Found 1 version(s) in C:\Program Files (x86)\UiPath\Studio.\Packages [ Nearest version: 20.10.1 ]
  • Found 1 version(s) in Local [ Nearest version: 20.10.1 ]
  • Found 0 version(s) in gallery/api/v2
  • Found 0 version(s) in Connect
  • Found 0 version(s) in /F/workflow/
  • Found 0 version(s) in Official

If i try to update, this leads to the Message in the Manage Packages “Package installation failure”

Alternatively:

NU1102: Unable to find package UiPath with version (= 20.4.7422.14731)

  • Found 1 version(s) in C:\Program Files (x86)\UiPath\Studio.\Packages [ Nearest version: 20.10.7585.27318 ]

  • Found 0 version(s) in gallery /api/v2
  • Found 0 version(s) in Connect
  • Found 0 version(s) in myget/F/workflow/
  • Found 0 version(s) in Official

Looks like something is wrong with your feeds. It can’t find the exact matching version for the packages. Are you able to share example project so I could test it on my end?

Dear Pawel,
i also tried to create a new blank process, i’ll get the same issue

We installed UI Path using the platform installer on a windows Server 2016 (1607) system
We connected is to our orchestrator and added a template mashine and allocate floating users to that machine.
Ui path is starting normal

I was able to open your process without any issue. Just to confirm that all is set properly. Could you show me you package feed configuration. Manage Packages → Settings → and show all configured paths etc.

I see you have Official feed turned off. Please try to enable it and then check.

13

previously all default feeds were “on”, which does not make any difference

Eventually you can check if there is anything like firewall or proxy which block somehow your feeds. I assume that you are on Enterprise Plan. You may be interested in opening ticket for Technical Support. Maybe it’s something our support could check.
