anyone else having update problems with Mint15 Mate & 16 Cinnamon or mate RC
 

Seems like my update is unable to find all the files required to do the update.
Maybe something goofy with files on update server or with my system?
says could not refresh the packages at times and other times unable to download some of the packages and update is cancelled.
W: Failed to fetch http:/
packages.linuxmint.com/dists/olivia/Release.gpg Could not connect to packages.linuxmint.com:80 (204.45.82.194), connection timed out

W: Some index files failed to download. They have been ignored, or old ones used instead.

Wutt to do? Wait? Could be servers are busy or doing upgrades?
Manual refresh doesn't seem to bear fruit!
If anyone is saavy here thanx for a reply.
I'm running Mint15Mate trying to run Mint16 Cinnamon and MateRC in Vbox. Just switched from using AMD proprietary driver to recommended one.

Is your network connection strong for the rest of the net?

Try running these.

apt-get update
apt-get upgrade

You must be root or just do

sudo su

Enter password

first before using apt.

upgraded Mint no longer have problem
