So, I trimmed back the URLs, looked around, and went with: deb http://depot-trinity.dotriver.eu/trinity/ubuntu lucid main deb http://depot-trinity.dotriver.eu/trinity-builddeps/ubuntu lucid main However: Err http://depot-trinity.dotriver.eu lucid/main Packages 404 Not Found Fetched 22.4kB in 2s (11.1kB/s) W: Failed to fetch http://depot-trinity.dotriver.eu/trinity-builddeps/ubuntu/dists/lucid/main/… 404 Not Found There is no "/lucid/" under .../trinity-builddeps/ubuntu/dists/ But, there is a "/lenny/", as in: http://depot-trinity.dotriver.eu/trinity-builddeps/ubuntu/dists/lenny/... Very strange. Is there a sub-dirextory naming error there? Would using: deb http://depot-trinity.dotriver.eu/trinity/ubuntu lucid main deb http://depot-trinity.dotriver.eu/trinity-builddeps/ubuntu lenny main be a Real Ugly Hack to proceed? I was afraid that _would_ cause me problems. But having an existing, local desktop Ubuntu 10.04 with Trinity 3.5.13.2 gives me (maybe) the ability to fix any strange problems that might appear -- if I have to give up trying to upgrade to Trinity 3.5.12 Thank you. I am looking for an explanation of that "lenny"... Happy New Year! Jonesy
