Error on updating Edge canary: Failed to cache the downloaded installer. Error: 0x800b0001.
I'm getting this infamous error
Failed to cache the downloaded installer. Error: 0x800b0001.
restarting Edge or computer doesn't help.
I can see the directory is created:
AppData\Local\Microsoft\EdgeUpdate\Download\{ID}\83.0.473.0
for some reason my Fiddler doesn't show me the URL of the file being downloaded either. so I would like to fix this without reinstalling Canary 🙂
Something funny actually happened! I installed Edge canary but with the welcome screen and icons of Edge stable and also without update core!
so what I did was to find the logs in here:
%LOCALAPPDATA%\Temp\MicrosoftEdgeUpdate.log
Special thanks to Deleted for helping me find their locations
then find the URL which was this: (yup it's that long)

edeccdca-d35a-456d-8f21-194f50233db8no extension whatsoever. so I decided to add ".exe" to the end of it because otherwise what can i do with a file without an extension. after that doubled clicking on it silent installed Edge canary.
but it says official build and has no "canary" word anywhere on it
that temporary fixed it, tomorrow or next time when there is a new canary update on the server I will try the online installer and if it fails again I have to keep doing this.
I'm still looking for the reason why this problem apparently only happened to me and an official way to take care of it.
I had no problems.
- I can help you regarding this problem
I suggest you try downloading the offline installer, then run it locally on your PC
a copy can be found at this link:
https://www.microsoft.com/en-us/edge/business/download HotCakeX Hello. I just did an update. I ended without mistakes.
- Well any idea how to fix it? I still don't know what even triggers that
found a topic that says:
"The problem is that the system certificate verification download file does not pass.It cannot be installed online."
https://techcommunity.microsoft.com/t5/discussions/edge-chromium-could-not-be-installed-0x800b0001/m-p/1054403I just uninstalled Edge canary, downloaded the online installer but at the end when download finished I'm getting the same error!
