Bad substitution #52

Hello,

I get the following log each time ydns_updater.sh runs:

/root/ydns_updater.sh: 70: /root/ydns_updater.sh: Bad substitution

I have checked the line, it is echo ${ret//[[:space:]]/}

I never got it previously, and I don't remember changing something in the system. Maybe some package is missing after an update?

I get the same error when I run sh ydns-updater.sh.
I don't receive an error when I run ./ydns-updater.sh or bash ydns-updater.sh.
