From the name of the file, tmp_sh, I would hazard a guess that some process has written a shell script of files to download, but that script has not been placed in a world-readable location. User _apt can't read it to perform the sandboxed download, so user=root has to do it instead. > Strange, the second install, even if providing a local file, is still > fetching the file from "deb.debian.org". So AIUI, the sequence is (user == root): . read the control file from the /path-to/foo.deb and obtain the package name, version and dependencies. . is that package/version locatable using sources.list? . if so, _apt downloads from Debian and caches the file as per usual. Install. . is /path-to/foo.deb world-readable? . if so, _apt "downloads" from /path-to/foo.deb. Install, no Warn. . if not, user/root performs an unsandboxed (no _apt involvement) "download" from /path-to/foo.deb instead. Install and Warn. Cheers, David.
