Why am I unable to update my Lumia 535?

[Windows Central Question]

I am having Lumia 535, I have installed windows Insider for windows 10 update and it shows the update available. is also finishes the downloading the update. but when the phone reboots the update interrupts and phone reboots again and shows the error message "we tried using your SD Card to perform the update, but something went wrong.(0x801882c1)"
I have formatted my SD Card thrice and also brought new SD Card but error is same all the time.

You need 1500 - 2000 MB free space on phone memory to perform OS update. Make some space in phone memory and remove the SD card.
