Can someone help me with this? I am not able to download hexedit. It seems like i'm a little confused with the changes in repos also.. i don't know which ones should be enabled and which should be disabled. # apt-get install hexedit Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: hexedit 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 26,9kB of archives............ E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
