Seems that the only way to succeed at upgrading these packages is to add the following line to /etc/apt/apt.conf
APT::Immediate-Configure "false"; Two observations: Seems that the logic for this APT option was recently reverted, if Google results for "immediate-configure" is any indication. Could it be that the "fix" actually broke the default behavior? The fact remains that cyrus-sasl2 is a very rare case that triggers this error in apt-get. It needs to be fixed. -- Dependency cycle prevents upgrade of libsasl2-2 https://bugs.launchpad.net/bugs/194140 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
