I installed Vmware it was working well, i updated/upgraded OS firmware, now it’s not working. i googled it and found the solution. before telling the solution i wanna tell why this is coming.

VMware Player has a nice auto-detection of kernel changes, and requests the user to compile the required modules in order to load them. This happens from time to time after a regular update of your system. Usually, the dialog of VMware Kernel Module Updater pops up, asks for root access authentication, and completes the compilation.

In theory this is supposed to work flawlessly but in reality there are pitfalls occassionally. With the recent upgrade to Ubuntu 13.04 Raring Ringtail and the latest kernel 3.8.0-21 the actual VMware Kernel Module Updater simply disappeared and the application wouldn’t start as expected. When you launch VMware Player as super user (root) the dialog would stall.

Solution is :

sudo vmware-modconfig --console --install-all

This solution worked for me.

My machine was VMware Player 5.0.2 build-1031769

I have a Ubuntu 13.04 that I just installed fresh. Now if I try to do anything with apt-get, it tries to connect to archive.ubuntu.com .. It stays at [Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase for like 2 minutes, after which it actually starts to communicate and download stuff …

Eventually it always connects, but in waits at the [Connecting to archive.ubuntu.com (2001:67c:1360:8c01::1a)] phase everytime for like 2 minutes !

I didn’t have this problem previously on Ubuntu 13.04, right after reinstalling the OS ..

Solution:

I figured out the problem. Posted below as an answer!

Running the following command in Terminal tells if IPv6 is enabled or not:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6

0 means its enabled, while 1 means its disabled.

To disable IPv6 from within Terminal, enter the following and reboot:

echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

After boot, re-run the first command, and it should be 1 now, after running this run

sudo sysctl -p

all output should be 1, now ipv6 is disable here.
