If I'm remembering the LSB correctly, then all programs on a linux box are 'SUPPOSED' to use the group name, instead of the UID/GID, to maintain cross-platform compatability. if the permission of the file is group readable (or read/writable), then it should work correctly. There are several ways to get around the problem, The quick-and-dirty way to fix this is to do a "chmod +r 'filename' ", and set the read flag for all users. A little more involved way, would be to do a "chmod 660 'filename' && sudo chown gene.1000 'filename' ", in pclos. This will give read/write access to user, and group. Then changes group to 1000, which would be valid on the Ubuntu machine. 640 would probably be more appropriate, if you do not intend to edit on the Ubuntu machine. Copy 'filename' to the Ubuntu machine, and then see what happens. The major downside to each of these workarounds, is that this would have to be done EVERY time you need to copy a file. A simple script could be written to make this easier. The permanent fix, would be to change the UID/GID on the Ubuntu computer, to force it to use 500, instead of 1000. Two ways to do it, are with the usermod command, using -u 500 -g 500 or manually editing the /etc/passwd, and /etc/group files directly: sudo cp /etc/passwd /etc/passwd.orig sudo cp /etc/group /etc/group.orig sudo vim /etc/passwd: gene:x:1000:1000:Your Name,,,:/home/gene:/bin/bash change to gene:x:500:500:Your Name,,,:/home/gene:/bin/bash sudo vim /etc/group: gene:x:1000: change to gene:x:500: Manually editing these files guarantees that you will need to chown your files back to gene.gene.
