Recording the session
It is strongly recommended that you use the
/usr/bin/script program to record a transcript of the upgrade session. Then if a problem occurs, you will have a log of what happened, and if needed, can provide exact information in a bug report. To start the recording, type:
# script -t 2>~/upgrade-wheezystep.time -a ~/upgrade-wheezystep.script
or similar. If you have to rerun the typescript (e.g. if you have to reboot the system) use different
step values to indicate which step of the upgrade you are logging. Do not put the typescript file in a temporary directory such as
/tmp or
/var/tmp (files in those directories may be deleted during the upgrade or during any restart).
