macOS Big Sur Installation Failed: 'An Error Occurred While Installing the Selected Updates'

[januarydrive7]

Ok I just jumped the gun and can confirm the Twitter link does work.

I'm waiting to see someone post the MD5 of the "official" installer.

hey guys the big sur update seems to have been pulled. I'm in Florida US, and I just went back and ran the software update prefpane and now it says my system is up to date with Catalina.

Finally...someone giving extra info thanks. Mine was stuck being unable to install and guarantee that is because it didn't fully complete the download - even though the system said it did.

I ran that command, clicked update (No VPN and I'm in UK) and it has started straight up from 3GB download. This proves that it had only downloaded that much before. I'm confident that if this completes it will now install but I will updated.

It says it will take 22 minutes to complete and is flying through the download.

Nope. Sudo didn't work for me.

Extra credits for the rest of the download? 😈😈😂😂

I legit think some of us might be stuck until the next .01 or whatever update rolls out :/

It's 2:30 AM now in Greece and I need around 3 more hours to complete the download.
Any ideas on how to stay awake? (LOL)

Get a coffee. I got one myself.

Well this is interesting. My software updates suddenly claims I have no internet and that my updates are managed externally.

Those of us that "supposedly" downloaded the FULL file earlier are still in purgatory. Won't even initiate a download because the broken file keeps trying to install first. I'll just pile on to the group asking how do we delete that file so it can start over! UGH

One more on the pile for that!

I'm also in Florida and it still seems there for me. Broken as ever though.

Quick Q:
Can anyone remind me where the installer file(s) are stored when I get the initial 'click to continue' screen?
I'd like to copy them onto another Mac...

Did you reboot your Mac? If not, do that and it should clear.

Try running

sudo softwareupdate --clear-catalog

and then restart preferences.

The OS installer downloads to the Applications folder.

 

[satsi]

That is already the .01 rolled out

oh well, i'll just wait since you're in Florida, how bad of a beating did you get from the tropical storm that went across today ? I mainly got rain and 15 to 23 mph winds not bad at all.

 

[nightfox818]

Try running

sudo softwareupdate --clear-catalog

and then restart preferences.

Thanks! That seemed to put it back. Not sure how or why it changed.

Yes. Happened to me. Clicked the little x button and redownloaded and now I am installing as expected.

The OS installer downloads to the Applications folder.

Mine before it crashed had said it downloaded 12.18 GB. I'm stuck in purgatory in Los Angeles.

there's a bug where Software Update App. doesn't populate the authentication headers in the request it sends to Akamai servers and those return an error "403" aka "Prohibited". I am assuming there was an issue with the previous update of Catalina that screwed up the communication protocols.

I got stuck there too after VPNing to Australia. And then I got the "Installation Failed" Message. Ugh
