Which version of rtslib/targetcli are you using?

It worked when installing Linux. Today this error suddenly appeared. There may have been a system update.

How to view the rtslib version?

Same problem here. This is Ubuntu 22.04 with a custom kernel.

@urb31075 @gkyildirim This was fixed in rtslib 2.1.75 more than 1 year ago. Ubuntu / Debian should update their packages
