Sophos Anti-Virus for Linux 10

What to do

The first thing to do is to check if the /tmp is mounted as noexec. To do this, run the command mount|grep tmp

If the result shows /tmp noexec, proceed in doing either of the steps or options below:

Remount the /tmp without noexec 

1. Mount the /tmp exec using this command mount -o remount,exec /tmp
2. Run install.sh, SophosInstall.sh or use the package manager of your choice to install the package rpm -i SophosInstall.rpm / deb -i SophosInstall.deb
3. Mount the /tmp noexec again using this command mount -o remount,noexec /tmp

Overwrite the TMPDIR variable

The TMPDIR is a variable used by the Sophos anti-virus for Linux install script to extract the archives for the installation. Another way to install the Sophos anti-virus for Linux when /tmp is mounted as noexec is to set the TMPDIR variable to a mount point which is not mounted as noexec. 

Note: If the TMPDIR has already been set to a location, restore it to its previous value.

1. Set the TMPDIR to /var/tmp by using the command export TMPDIR=/var/tmp
2. Run the installer as described above.
