Thanks for filing this bug in Ubuntu. Indeed there was a fork error: [ 302.784667] cgroup: fork rejected by pids controller in /user.slice/user-1000.slice/session-2.scope [ 313.769755] cgroup: fork rejected by pids controller in /user.slice/user-1000.slice/user@1000.service
You seem to have hit a resource limit. Do you have some custom configuration around resource limits, perhaps around DefaultTasksMax? Or a lot of processes running as the user 1000? Does the following retry attempt fix it? sudo apt update sudo apt -f install ** Changed in: apache2 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to apache2 in Ubuntu. https://bugs.launchpad.net/bugs/1779246 Title: package apache2-utils 2.4.29-1ubuntu4.2 failed to install/upgrade: dpkg-deb --control subprocess returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1779246/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
