The pic shows it, but basically, after I install the package the tab is just gone and I can’t continue with XR setup. I’ve tried reinstalling Unity and Unity Hub and installing both 2019.3 and 2020 version, it’s the same situation. Anyone got any ideas?
Here are the logs in txt format, so I can upload them here
5810998–614965–upm - Copy.txt (1.29 KB)
5810965–614962–Editor - Copy.txt (55.5 KB)
I also deleted every single other package and just installed XR one. I got some new errors in the Unity Editor:
Attaching new logs as well.
5811004–614986–upm - Copy2.txt (3.29 KB)
5811001–614977–Editor - Copy2.txt (167 KB)
Does it come back after restart of the Editor?
BTW, any errors in compilation or package import will cause package manager to report the package as installed but the package will not activate till all errors are dealt with. I can see that both pics show errors in the log, which is halting package activation. You will need to make sure all errors are gone and it should work after that…

@joejo I tried Editor restart. I tried Editor reinstall. Along with Unity Hun reinstall, along with clearing any data from AppData and Registry Editor. Nothing.
For fixing the errors: I’ve tried mostly everything on google search’s first page. But the main fix suggest using Malwarebytes to scan for viruses, which I did, and quarantined everything…
Still no luck in fixing those errors or installing XR Plugin Management
Until the errors are resolved the package won’t activate (this is general for all packages and nothing specific to XR Plug-In Management).
If you look in the upm log files you pasted you can see the package management errors that may be causing you issues. I’ve never seen anything like those before and have no real experience with what may be going on. Looks like some sort of permission issues somewhere but not much else I may be able to tell you. Definitely not something I have ever come across.
May want to cross post here: Unity Engine - Unity Discussions
Is there a reason the system can’t detect and report this?
I would expect - (via the “principle of least surprise”) - the installed-but-inactive items to have greyed-out text in the settings window, and when clicked you get a panel that says literally a copy/paste of your description in this thread 
because it’s clear, actionable, and makes sense.
Not disagreeing in any way, but I would still bring this to Unity Engine - Unity Discussions so that appropriate internal parties have this info as well.
Sure. I was just wondering if that was a limitation of PM (that you can do nothing about), or whether it was possible with PM but not something you’d decided to do yet.
Also: since PM doesn’t work with the asset store yet, I’m putting the absolute minimum time into PM possible until it’s ready for widespread use outside Unity’s internal projects. e.g. I still can’t get the official Unity packages that used to be built-in (e.g. UnityUI) to build correctly because of PM (seems that most other people can’t either - most seem to be using the 2018.x versions of UnityUI, even in 2019/2020 because no-one can get it to work with PM), and there’s no official docs on this from Unity yet (Even though it broke in 2019.2, so we’ve been waiting quite a while for clean solutions).
XR is core to my projects, so I’m highly motivated to report bugs/feature-requests/etc there. PM? Can’t use it, and it’s been broken in big ways for more than a year, so … a lot less motivated :).
came here with the same issue.
Unity version: 2019.3.4f1
Tried to follow
https://developer.oculus.com/documentation/unity/unity-single-pass/?locale=en_US
pressed install xr plugin management, and after it was done, and I added some includes to some oculus cs files, i see no errors at all, but no sign of xr plugin managment
the package manager says that latest is installed. Should it be under project settings, or has it been moved anywhere else?
@carrotstien Yup, it’s still there.
What fixed it for me was making another Windows profile. It turned out my default one, even tho it was Administrator, had some messed up permissions. So making a clean normal (not admin) account and using Unity through there fixed all my issues.
Hey, in case anyone runs into this problem, what fixed it for me was downgrading my XR Pluging management to 3.2.16 in Unity 2020.1.3 . The 3.2.17 has an error and it will not install correctly.
