/var/log/dist-upgrade is empty. Before I got this bug I was downgrading ff from 7 to 3.6. I followed an instruction for 11.04. I think it is because I mixed up versions of Ubuntu. The instruction is: Step 1: Edit your software sources to add Maverick Open your sources.list file: sudo gedit /etc/apt/sources.list
Add the folowing three lines: # Maverick, used for firefox and firefox-branding deb http://ftp.iinet.net.au/pub/ubuntu/ maverick main deb http://ftp.iinet.net.au/pub/ubuntu/ maverick-updates main Save and close the file Step 2: Pin the packages firefox and firefox-branding Create the pin file for firefox: sudo gedit /etc/apt/preferences.d/firefox Add the following: Package: firefox Pin: release n=natty Pin-Priority: -10 Package: firefox Pin: release n=maverick Pin-Priority: 900 Save and close the file. Create the pin file for firefox-branding: sudo gedit /etc/apt/preferences.d/firefox-branding Add the following: Package: firefox-branding Pin: release n=natty Pin-Priority: -10 Package: firefox-branding Pin: release n=maverick Pin-Priority: 900 Save and close the file. Step 3: Check your apt policy to make sure it worked Update your apt cache: sudo apt-get update Show the apt policy for firefox: sudo apt-cache policy firefox Sample output: sudo apt-cache policy firefox firefox: Installed: 5.0+build1+nobinonly-0ubuntu0.11.04.2 Candidate: 3.6.18+build2+nobinonly-0ubuntu0.10.10.1 Package pin: 3.6.18+build2+nobinonly-0ubuntu0.10.10.1 Version table: *** 5.0+build1+nobinonly-0ubuntu0.11.04.2 900 500 http://ftp.iinet.net.au/pub/ubuntu/ natty-updates/main i386 Packages 500 http://ftp.iinet.net.au/pub/ubuntu/ natty-security/main i386 Packages 100 /var/lib/dpkg/status 4.0+nobinonly-0ubuntu3 900 500 http://ftp.iinet.net.au/pub/ubuntu/ natty/main i386 Packages 3.6.18+build2+nobinonly-0ubuntu0.10.10.1 900 500 http://ftp.iinet.net.au/pub/ubuntu/ maverick-updates/main i386 Packages 3.6.10+build1+nobinonly-0ubuntu3 900 500 http://ftp.iinet.net.au/pub/ubuntu/ maverick/main i386 Packages The line you are most interested in is "Candidate". This indicates the package that apt ranks as the installation candidate. Repeat this check for firefox-branding sudo apt-cache policy firefox-branding Step 4: Install firefox 3.6 Remove firefox 5.x: sudo apt-get remove firefox Install firefox 3.6: sudo apt-get install firefox And you're done.
