Upgrade debian stable to testing.

Upgrade the stable version of debian to the testing version-the technology of the Linux release version-Debian information. For more information, see the following. The stable version of debian is very stable, but there is also a problem that the software version is too old. As a beta test environment of the next stable version, the testing version is actually much more stable than the unstable version, and it does not appear unstable in many linux releases, in fact, many ubuntu-desktop versions correspond to the testing version, which is quite stable.

To upgrade my etch stable to lenny testing, the following actions are performed:

First, modify the stables or etch source in sources. list to testing (change to lenny)

Then atpitude dist-upgrade

A bunch of prompts, umet, are filtered and deleted. Run this command.
Aptitude install apt-utils aptitude-doc-en libc6 libc6-dev libc6-i686 locales python-apt binutdatatzd

Then try aptitude dist-upgrade until the umet prompt is not displayed and the score is not negative. Start upgrade:
Aptitude dist-upgrade

To answer a lot of questions about software initialization and installation, I usually use yes. I have a log to answer no, but it doesn't matter.

Pam update will damage the pam settings of vsftpd and will not allow updates.

Vimrc updates are also ignored, and my own configuration is retained.
/Etc/modprobe. d/aliases update is also default. I didn't use a special mod
Vulnerable random number generator default Selection
/Etc/sysstat selected by default

/Etc/X11/xdm/Xaccess is also selected by default, with no special configuration
