I live in Egypt. we have a country specific server here. I used to download everything from there. but when I got to download encryptfs
, synaptic said the package could not be authenticated, so I changed the apt mirror to default ubuntu server and the packages could now be authenticated.
Due to the fact that we live in a country with mass surveillance and no laws to protect privacy or human rights, I have been thinking that maybe backdoors were placed in the unauthenticated package. so I have decided to re-download all the unsigned packages from the main ubuntu server, however this doesn't seem to be addressed anywhere.
So, in this regard, how to re-install packages?
