Logjam 4.5.3-2 never made it to the gutsy repository
Binary package hint: logjam
After reporting bug #176621, I have found that it has already been fixed and was supposed to be in gutsy. Launchpad claims this has already happened: https:/
See in the repository:
Note that the source package is at logjam_4.5.3-2.dsc, but the binaries are at logjam_
So it can be seen that the source and binary packages are out of sync.
