when I install release using akvcam-installer-cli-linux-1.2.4.run I get error about bad substitution.

./setup.sh: 417: Bad substitution

Script has shebang #!/bin/sh but use Shell Parameter Expansion which is not part of POSIX and is specific for bash.
on Ubuntu default shell is dash so this fails

work around: force running by bash

bash setup.sh

It's marking this line.

echo "Installing missing dependencies: ${missing_dependencies// /, }"

Is there a generic way of making string substitution or I must force bash in the shebang?

[matlad]

best thing i can thing of is using sed
example

 echo "Installing missing dependencies: $(echo ${missing_dependencies}| sed 's/ /, /g')"

Fixed in latest release.
