I have a packageA, which depends on apache2-mpm-prefork. packageA was installed. Now I tried to install apache2-mpm-worker, but the output is:
me@XXX:~$ sudo apt-get install apache2-mpm-worker Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: ... Use 'apt-get autoremove' to remove them. The following packages will be REMOVED: apache2-mpm-prefork packageA The following NEW packages will be installed: apache2-mpm-worker Why? How to install apache2-mpm-worker without touching packageA? Thanks
