Hello!

504 indicates that there was a timeout error between a proxy somewhere and the server you were trying to reach. I suspect that there is a problem at offensive-security.com. You should be able to update what you already have. You might try later to see if that url can be reached.

I hope you are sure of the legitimacy of that repository.

Cheers!

[faris2]

ihave legitimacy of that repository. but my problem tel now not solved

[bapoumba]

I cannot get to the repo either.
Have you installed anything from them ? Best route would be to remove these packages, remove the repo from your sources.list and update/upgrade again.

[faris2]

sorry how to do it? i'm beginner at ubuntu:(

[faris2]

no any one know?

[bapoumba]

First question was : have you installed any packages from these repos ?

To remove or disable a repository you can either use the graphical interface https://help.ubuntu.com/community/Repositories/Ubuntu#Removing_.26_Disabling_Repositories or use the command line : https://help.ubuntu.com/community/Repositories/CommandLine

Please post the output of your sources.list file : cat /etc/apt/sources.list

[faris2]

Apparently, folks have been having trouble getting this repo for quite awhile.
