I am facing the same problem. Are you still facing this problem now?

[lanistor]

Resolved? I have the same problem? Reopen it ?

Same problem here. Using the classique options for electron builder an receiving this kind of stack randomely among my app updates:

sha512 checksum mismatch, expected

Still the same problem after updating to :

"electron-builder": "21.2.0",
"electron-updater": "4.1.2",

I insist on the "Randomly" property of the bug. The last time I reproduce was like :

• Update version of app
• App is being updated correctly
• Close the app
• Reopen the app > Crash when check for update (sha512 error mismatch)
• Wait 5 minutes
• Reopen the app > everything is correct

EDIT : Seems that's i had cache problems with the latests.yml

[alexandermckay]

I also have this problem. @Pandakls how did you fix it ?

[Pandakls]

Actually, when the server is making a new update (with new checksum) the client was getting the new checksum detecting the uptade. But when asking the server it's the old version that was still delivered. So i forced clear server cache on each update so it wasn't incoherent anymore.
