Have you ever encountered the frustrating error message “invoke-rc.d: could not determine current runlevel” while managing services or packages on your system? This issue can impede smooth operations and cause confusion. But fret not, as we delve into potential solutions and strategies to address this issue.
Let’s explore some insights and actionable steps to overcome this roadblock.
The error message “invoke-rc.d: could not determine current runlevel” typically occurs when managing services or system initialization scripts. Let’s explore some possible solutions:
Check Permissions:
Ensure that you are running the command with sufficient privileges (usually as root or using sudo). If not, try running the command with elevated permissions.
Reconfigure Services During Install:
To disable reconfiguration of services during installation, set the RUNLEVEL variable to 1 before installing or upgrading a package. For example:
RUNLEVEL=1 sudo apt-get install mysql-server-5.7
If you encounter issues with a specific package (like mysql-server-5.7), you can also manually reconfigure it using:
dpkg-reconfigure mysql-server-5.7
Specific Case (Docker):
If you’re encountering this issue while uninstalling Docker, consider the following steps:
sudo su
The error message “invoke-rc.d: could not determine current runlevel” typically occurs during package installation or configuration. It indicates that the system couldn’t determine the current runlevel, which is essential for managing services.
Here are some insights and potential solutions:
MySQL Installation Error Example:
invoke-rc.d: could not determine current runlevel
* Stopping MySQL database server mysqld [ OK ]
/var/lib/dpkg/info/mysql-server-5.7.postinst: line 191: /usr/share/mysql-common/configure-symlinks: No such file or directory
dpkg: error processing package mysql-server-5.7 (--configure):
installed mysql-server-5.7 package post-installation script subprocess returned error exit status 127
dpkg: dependency problems prevent configuration of mysql-server:
mysql-server depends on mysql-server-5.7; however:
Package mysql-server-5.7 is not configured yet.
Possible Solutions:

dpkg-reconfigure mysql-server-5.7
Other Scenarios:

Specific Package Issues:
The error message “invoke-rc.d: could not determine current runlevel” can be frustrating, but there are several strategies you can try to resolve it. Let’s explore some advanced troubleshooting steps:
Check RUNLEVEL Variable:
RUNLEVEL
environment variable.RUNLEVEL=1 sudo apt-get install mysql-server-5.7
dpkg-reconfigure mysql-server-5.7
Workaround for Docker Containers:
invoke-rc.d
(which doesn’t work in containers with no runlevels) before attempting the service
command (which does work).service
command.Specific Package Troubleshooting:
The “invoke-rc.d: could not determine current runlevel” error can occur during package installation or configuration. It’s related to the system’s attempt to determine the current runlevel, which is a concept from traditional Unix-like systems. Here are some ways to address this issue:
Using the RUNLEVEL Variable:
RUNLEVEL
variable before installing the package. This disables reconfiguration of services during installation.RUNLEVEL=1 sudo apt-get install mysql-server-5.7
dpkg-reconfigure mysql-server-5.7
Workaround for Docker Containers:
service
command instead of invoke-rc.d
. This change should resolve the issue.Policy-rc.d Solution:
/usr/sbin/policy-rc.d
with the following content:
#!/bin/sh
exit 0
policy-rc.d
.In conclusion, navigating through the error message “invoke-rc.d: could not determine current runlevel” demands a systematic approach and keen troubleshooting skills. By checking permissions, leveraging the RUNLEVEL variable, and tailoring solutions to specific scenarios, you can effectively manage services and packages on your system. Remember, understanding the intricacies of system initialization scripts and service management is key to resolving such challenges.
