Bug Description

Binary package hint: dash

ATI driver 8.29.6 installer script fails as follows:

root@ariesduo:~# cd /usr/local/src/

root@ariesduo:/usr/local/src# ls
ati-driver-installer-8.29.6.run

root@ariesduo:/usr/local/src# sh ati-driver-installer-8.29.6.run
Creating directory fglrx-install
Verifying archive integrity... All good.

./ati-installer.sh: 176: Syntax error: Bad substitution
Removing temporary directory: fglrx-install

This is due to /bin/sh symlinked to /bin/dash . Apparently dash has some problems in the for loop. The solution is to symlink /bin/sh to /bin/bash and the driver installs fine.

Installer appears to be available from: https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver-installer-8.29.6.run, and is about 55MB large.

I'm afraid this is a bug in the installer, which makes bash-specific assumptions, rather than a bug in dash.

The culprit is:

                for dir in ${PATH//\:/ }; do

This is not standard shell syntax, but is a bash extension, and dash is right when it complains that it is a "Bad substitution".

Changed in dash:
