Dunno about install/upgrade of squid-package on Ubuntu, but always installed my squid on ubuntu from src. As you have a running version already, you only should backup squid.conf to another location to be used with new squid. Do a "squid -v" to note actual configure-options, to be used for new squid as well. And copy /etc/init.d/squid to a safe location, also to be used for your new squid later on. You might now deinstall/delete your running squid then, incl. cached files. (Remove the service and delete the package) Then ./configure #with old config-options make make install new squid, copy old squid.conf to /usr/local/squid/etc Copy saved /etc/init.d/squid back to /etc/init.d/squid And re-install service-squid -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/need-help-with-ubuntu-upgrade-procedure-tp4665324p4665326.html Sent from the Squid - Users mailing list archive at Nabble.com.
