Package installation keeps failing

[nicolas.fangel]

First of all, im brand new to UI-path and have been using it for about a month now, so bare with me.

Now:
Last week, when I opened UI Path on my work-laptop I encountered this error:

“21.10.0+Branch.master.Sha.5a7d7ca17ff690283740729e7884a6c161b22d46
The feed htps://packages.uipath.com/activities [htps://packages.uipath.com/activities] lists package ‘UiPath.System.Activities.21.4.1’ but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.”

Four packages would not install (see pictures provided)
After trying to install them in “Manage packages”, Ui Path presented 250 new errors with missing packages.

Furthermore, my processes began to be labled: “Windows_Legacy”, “Local” and “VB”

I found this guide and uninstalled UIPath along with deleting the %userprofile%.nuget
When I reinstalled UI Path IT WORKED! The process ran again with no problems.

BUT THEN, a couple of days later the package failed to install again.
I followed the guide once again and installed UI Path. But now, the packges would still not install.

I did it again, and again, but i would not work.
I tried finding as many UI Path folders/files and deleted them. Nothing helps.Processing: uipath fail.docx…()

Now, im stuck again…

This was the guide i found: Package Install Failure? - #3 by lakshman

Check the original project.json and install those dependencies first, make sure the official feed is selected in the Source inside Manage Packages
OR
Try downgrading the version to see any of that works

Hi @nicolas.fangel,

Welcome to the community!

Check that your packages list in Manage Packages matches the list of packages in the “project.json” file. Install the missing ones, and check whether you can update your packages in Manage Packages. The package will have a blue arrow like the package below:

It is also worth checking that your Default package sources, found in Manage Packages > Settings, are all checked:

If you check any of these items that are unchecked, you will need to check for updates in the packages list again

[nicolas.fangel]

Hello William.coulson,
Thank you for the quick answer.
My “Default pacakge sources” are all checked, but the “orchestrator” is checked, but greyed out?
Furthermore, my json and packages seem to match? (Se image1)
When i try to update the packages (blue arrows), UI Path says the following:

"21.10.0+Branch.master.Sha.5a7d7ca17ff690283740729e7884a6c161b22d46

Hi @nicolas.fangel,

For the error, see if this topic helps:

[Solved] the feed lists package but multiple attempts to download the nupkg have failed

I consulter this case with our team and it looks like you were not able to download the package from Robot. Most likely due proxy/internet configuration. The workaround you have used works as the package might have been found by Studio on another feed and since the nuget folder is shared between Studio and Robot it will work. But this is not a proper solution as this can break if the nuget cache is cleaned. You should download the specific package and place it on Orchestrator if you are not abl…

I suspect the Orchestrator package list being greyed out is linked to the error you are getting. If the topic doesn’t help, I would try raising a ticket with UiPath technical support (@Pablito suggests this in the topic I have linked).

Hope this helps

Hi @nicolas.fangel,

I have just faced a similar packages issue when I was installing UiPath for a new user, and it came up because of the permissions for the user account. I’d recommend checking your permissions on your account

[postwick (Paul Ostwick)]

Looks like your machine is blocked from accessing myget.org

[nicolas.fangel]

Hello William,
I have written to our Service Department and asked for permission to access myget.org. A quick browser search gives me a company blockage. I will return with their answer as soon I recieve it.

[nicolas.fangel]

Hello again william.coulson,

I have now been granted access to “myget.org” and this fixed the project dependencies. Thank you, all!

Unfortunately, this has revealed another package problem.
I get: “Error: ’407 Proxy Authentication Required’”

It must be a problem related to the firewall/security-protocol? (It’s wierd that this first happens now…)

Effectively, new processes/projects cannot use basic activites such as “Open Browser”. They simply does not exist. My current project can though which must be due to its cache repository?

[william.coulson (Will Coulson)]

Hi @nicolas.fangel,

Yes, I imagine your firewall/security protocol is blocking it. The issue with the other packages missing may be down to whatever you have stored in your .nuget folder, I would recommend you or your service department getting in touch with technical support to work out this issue. Apologies that I can’t help any more than that
