This tutorial will explain how to upgrade Ubuntu Server from Feisty to Hardy
Step 1: Feisty to Gusty Upgrade
first be sure your feisty up-to-date
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
if everything ok, ready for upgrade to gusty.
nano /etc/apt/source.list
all change “feisty” to “gutsy”
save and exit (ctrl-x, yes)
sudo apt-get update
sudo apt-get dist-upgrade
(one package doesn’t upgrade : mailscanner
but this step its fix:
nano /etc/init.d/mailscanner
around 124 line (do_stop function) add ‘exit 0′
do_stop()
{ exit 0
# Return
# 0 if daemon has been stopped
# 1 if daemon was already stopped
# 2 if daemon could not be stopped
# other if a failure occurred
start-stop-daemon –stop –retry=TERM/30 –name $NAME
RETVAL=”$?”
[ “$RETVAL” = 2 ] && return 2
# Remove lockfile for cronjobs
if [ $RETVAL -eq 0 ]; then
rm -f /var/lock/subsys/mailscanner
touch $stopped_lockfile
fi
}
save and exit.
and re-apply
sudo apt-get dist-upgrade
command. its works. there some warning related with mailscanner but not important (for now)
and reboot
my server is gutsy, now.
step 2. Gutsy to Hardy upgrade
nano /etc/apt/source.list
all change “gutsy” to “hardy”
save and exit (ctrl-x, yes)
sudo apt-get update
sudo apt-get dist-upgrade
one package doesn’t upgrade : mailscanner
but no problem
reboot
mailscanner fix:
first backup your mailscanner folder. (/etc/mailscanner)
sudo cp -R /etc/mailscanner /etc/mailscanner_backup
sudo apt-get remove –purge mailscanner
(if removing results same error, around 124 line (do_stop function) add ‘exit 0′)
wget http://http.us.debian.org/debian/pool/main/m/mailscanner/mailscanner_4.68.8-1_all.deb
sudo dpkg -i mailscanner_4.68.8-1_all.deb
and
nano /etc/default/mailscanner
# Uncomment this line once MailScanner has been fully configured.
#
run_mailscanner=1
save and exit..
replace your backup mailscanner folder (/etc/mailscanner)
sudo cp -R /etc/mailscanner_backup /etc/mailscanner
/etc/init.d/mailscanner start
