I have tried following solutions:

apt-get clean
apt-get autoclean
then tried updating again. But still no success.

Please provide me some solution.

Which mirror of the repo are you using?
This is auto selected based on your GeoIP.


Click on both of the links below:
http - http://http.kali.org/README.mirrorlist
security - http://security.kali.org/README.mirrorlist


It will say something like:

List of best mirrors for IP address xxx.yyy.zzz.abc, located at 12.345679,-0.98765 in <COUNTRY>:
Found 1 mirror which handle this country:

hxxp://ftp.domain.com/kali-security/README (na, prio 100)

Found 5 mirrors in other countries, but same continent (EU):

hxxp://ftp1.domain.com/kali-security/README (na, prio 100)

Ive justed both mirrors (http://mirror.hust.edu.cn & http://mirror.hust.edu.cn), and they are working okay for me.
Are you currently still facing the same issue?

[san]

The issue appears to be because of some firewall/IP issues. I am getting the pub IP dynamically, and only in some IPs the issue seems to occur.
As the upgrade process is so slow, it is taking too much time.

Thanks
