Thanks for filing this bug in Ubuntu. According to the attached logs, you seem to have a syntax error in your squid configuration file:
Dec 04 12:56:01 anonymus squid[4378]: * FATAL: Invalid ACL type 'acc1' Dec 04 12:56:01 anonymus squid[4378]: FATAL: Bungled /etc/squid/squid.conf line 1183: acl not acc1 url_regex .facebook.com In the config: acl networking src 192.168.8.0/24 acl not acc1 url_regex .facebook.com acl not acc2 url_regex .youtube.com Once you fix that syntax, try: sudo apt update sudo apt -f install and that should fix it. ** Changed in: squid3 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1736077 Title: package squid 3.5.23-5ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/1736077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
