soo many errors while running update in kali

Kali isn't supported here or any of the Ubuntu community forums. It's support is entirely separate from Ubuntu's

I suggest you post on the Kali forum here
https://forums.kali.org/

None of the Ubuntu based distributions are supported here

I confirm that Kali Linux is not supported in this Ubuntu question area.

I still want to help:
There is an error in the configuration of your package management system.
Apparently there was a confusion between i386 and 1386.
The command
sudo dpkg --remove-architecture 1386
will most probably help.

thanks..i have get rid of all these

Please ask at kali.

Last remark from my side:

Do a web search for "Kali and PPA" and you will find several pages telling that it does not make sense to add a PPA to Kali Linux, because Kali Linux is based on Debian and not on Ubuntu.

Remove all references to PPAs from your package management configuration and all other junk files from the related directories and the errors will disappear.
