Package Manager missing in UI

I have unity 2018.1.1f1 I cannot seem to find package manager in the windows pull-down menu. Is anyone else experiencing this?

 

I just downloaded Unity 2018.2.0b9 and having same issue. The Package Manager disappeared from my Windows pull down

 

2018.2.0f2 still have the same issue. can someone from unity follow up on this?

 

I tried that, and now Unity won't even start that it crashes, please help, i have a presentation due next week and i was close to finishing my project

 

I'm using Unity 2018.1.6f1 and having this problem. I upgraded the postprocessing stack v2 yesterday using the package manager...then today I'm missing the Package Manager in the Window menu
and I get lots of timestamp warnings and this error:

Assembly has reference to non-existent assembly 'com.unity.postprocessing.Runtime' (Packages/com.unity.render-pipelines.core/CoreRP/Editor/com.unity.render-pipelines.core.Editor.asmdef)

 

I have exactly the same problem, and did what you did

 

ok so the fix I found: package manger notshowing: open the manifest.json file for the affected project in a text editor, and remove the package-manager-ui entry from there if there is one.

 

Help/Reset Packages worked for me thanks

 

I dont have the Package manager either, i used "Reset Packages to defaults" but it doesnt work. I had it but after i installed the Math package it didnt appear anymore. I use 2018.2.0f2
I tried removing the package manager from the json and even removing the json but nothing works

 

No package manager for me. Submitting bug report. Any editor version, all official recommendations tried.

 

i installed other version and worked, maybe works reinstalling the same version

 

same here in 2018.3 please help !

 

Still an issue on Unity 2018.4.12f1 (64-bit); Clean Install, New Project.

-Resetting Packages to Defualt does nothing.
-The fix Noted here: https://docs.unity3d.com/Manual/upm-errors.html does nothing.
-Launching via Unity Hub / Unity exe with Admin does nothing.

I have multiple versions of Unity installed.. 2017-2019, perhaps the problem lies there?

Quite saddening to see this is still an issue. If it's not broke don't try to fix it with a new broken / bad implementation. This is costing significant time to your users if you just google the problem, lots of issues with this system; I've used Unity since ~3.0 or so, this is the first failure which has cost me significant time. Hope this is not a sign of the future over at Unity.

 

Hi Karl and thank you for your response and time. Sincerely.

Unity 2018.4.12f1
There are no specific / detailed error messages, only 4 time stamps in the console.



That might indicate something to you. Also, is there anything specific we should look for in the logs?

If you perform the fix found on UPM-Errors.html for "Package Manager missing or window doesn’t open", it will result in an error: "Project has invalid Dependencies", and when you re-import it results in the same error. You then cannot re-open the project.

The log after the above fix was applied and project fails to open:

I was just very surprised such a vital mechanic has issues out of the box and there was no readily available solution which worked. I don't believe I will be investing any more time into this though and can only hope the information here may help someone else in the future.

I had been using 2018.4.23 fairly stably for some amount of time and recently started running into this.

I'm not sure what triggered it - the only thing I can think of is I had a Unity crash mid build recently.

Package Manager is not visible in Window.

Additionally, UIs for packages I've installed via Package Manager are all messed up or inaccessible (e.g. ProBuilders, ProGrids, OpenVR Desktop, Oculus VR desktop etc.) - e.g. they don't show up in the Tools dropdown, their components' custom editors don't show up as expected, etc.

Resseting all packages temporarily fixes the issue but:

1. It's awful, scary, and requires me to do quite a bit of auditing as resetting TextMeshPro and ProBuilder breaks parts of my project.
2. Is not a long term fix. The issue comes right back up the next time I open the project.

Really frustrated - have lost a whole weekend of work on a project I've been working on for almost 2 years and now just worried I'm going to lose a ton of work in general. Have been backing things up but it's so discouraging to lose a whole weekend when you only have weekends to work on a project.

Will try to get some logs to share.
