Please explain this a bit. Where are the configuration files for cabal install. I tried to enter the line in the terminal and it apparently it accepted i.e gave no error but then running cabal update results in this error No action for prompting/generating user+password credentials provided (use: setAuthorityGen); returning Nothing cabal: Failed to download index 'ErrorMisc "Unsucessful HTTP code: (4,0,7)"' This is the first time I am using cabal so I am almost completely blank for it. Thanks Azeem

My university requires the students to use internet through an authenticated http proxy. How do I configure cabal for that? I am using Ubuntu. Please be detailed about it.

Do you mean Cabal or cabal-install?

Assuming the latter:

export http_proxy=http://${username}:${password}@${proxy_address}
