Good time of the day. I try to install perl from testing repo but the following error: Could not perform immediate configuration on 'perl'. Please see man 5 apt.conf under APT::Immediate-Configure for details. I did try to enable/disable the parameter in /etc/apt.conf but w/o success. How I can do this? - In the found pages on the web they suggest to make sidt-upgrade but would not upgrade the dist... Thanks for Your time.
