Software Updater did it again this morning; no authentication demanded.
Here are the circumstances: Last thing I did before shutting down Trisquel yesterday was to finish the filing of some 45,000 messages from an old mailbox into Icedove. This morning I started Trisquel, downloaded about twenty email messages from several sources, including some benign spams that I marked as such and then deleted, and played a few games of freecell (my standard method of "warming up" the computer). Then I opened Software Updater and clicked "check for updates," whereupon it opened up with a list of software for HP printers and proceeded to download and install some 38MB, all without asking for authentication. Nobody else uses this computer, and I had not used Terminal and sudo apt-get update beforehand, so there was no leftover authentication for Software Updater to sniff out. There is no other flaky behavior going on that I know of, except that Icedove's count of remaining messages in the imported oldmail file was off by one after I moved the last visible email message.
