Bug#869741: apt: cannot update and install package

[Brianajie Waluyo <brianajie.w@gmail.com>]

Dear David, 

Thanks for the solution.

It's works and i suspect with virtualbox keys, because its repeat with this bug.

Maybe need to edit virtualbox key segment on debian wiki page.

Best regards,

Do you happen to have run synaptic recently, perhaps adding a repository
or similar such with it? We had recently users who did and had those
symptoms (guessing, as you have "helpfully" truncated the apt output
– don't do this in bugreports, always show the complete output).


As root (or via sudo) you should run:
        ls -l /etc/apt/trusted.gpg{,.d}
        file /etc/apt/trusted.gpg{,.d/*}

My guess is that one of those files is a keybox file which apt can't deal with
– and to top it of the keybox file is probably empty. Very likely the
/etc/apt/trusted.gpg file which tends to not exist nowadays, so after those
two commands lets directly try moving the file out of the way:
        mv /etc/apt/trusted.gpg{,.bak}


Hopefully that helps already. If not the output of the earlier two might
help us.  If "apt update" still fails please add: -o Debug::Acquire::gpgv=1
and include the full output (beware, that can be a lot) in a followup.


Best regards
