We have purcahsed the dell R710 rack server on this installed ubuntu server 10.4 LTS this is for the mail server (zimbra mail server) please suggest me which will be the best option for the complete upgradation
1.sudo aptitudue update once done sudo aptitude upgrade
2. sudo apt-get update once done sudo apt-get upgrade
Please suggest me whoch one is the better option.
Also for another few months we cannot afford to purchase the landscape subscription from the ubuntu but iam aware one month trail is available is it a good idea to subscibe for one month pu this production server on to the one month subscription so that will get all the updates.
Please suggest me on above 1 and 2 and also about the last regrading the trial subscription and after one month unsubscribe. Please help
