>From the Debian commit: https://anonscm.debian.org/cgit/apt/apt.git/diff/?id=78db351 which is supposed to be a reworded less scary message:
- _error->WarningE("pkgAcquire::Run", _("Can't drop privileges for downloading as file '%s' couldn't be accessed by user '%s'."), + _error->WarningE("pkgAcquire::Run", _("Download is performed unsandboxed as root as file '%s' couldn't be accessed by user '%s'.") For the non techies (says the huge majority of Ubuntu(s) users), that new reworded message is as scary as the first one !!! David (maintener) should completly silence that warning for the common users, and consider it only as an internal/debugging warning.
