Re: --set-selections - help needed to use this

I am installing on a new box. I have copied the installed_packages.txt from
the old box onto a CD. (I am physically 10 miles away from the old box)
I am failing in using teh list to install. I navigated to /media/cdrom0, then
#dpkg --set-selections < installed_packages.txt
#apt-get -u dselect-upgrade
After the first, the system complained that the file is read only. But I only
want to read it, surely? And after the second command 0 files were
Are you sure it wasn't just letting you know that you were reading from read-only media? The other option would be to copy the file from /media/cdrom0 to /root and do your --set-selections from there. But it really shouldn't matter.
As for the second, I have never used the -u. And according to the apt-get man page:
Show upgraded packages; Print out a list of all packages that are
to be upgraded. Configuration Item: APT::Get::Show-Upgraded.
As other posters have suggested, try running it without the -u.
