Upgraded the following packages: tdeadmin-trinity (4:14.0.1-0debian7.0.0+0) to 4:14.0.1-0debian7.0.0+0 tdegames-trinity (4:14.0.1-0debian7.0.0+0) to 4:14.0.1-0debian7.0.0+0
And if I simply hit the apply button, it will do it again and again. I nuked those two files in /var/cache/apt/archives by hand and it went away. Those were quite long filenames, and contained some odd characters. The dash is a legal char, but is the + sign? I don't know.
Cheers, Gene Heskett
