[Solved] Linux program error: dpkg is interrupted. You must manually run ‘sudo dpkg — configure – a’

The Linux program reports an error: dpkg is interrupted. You must manually run ‘sudo dpkg — configure – a’ to solve this problem.

Run the following command to resolve the error

sudo rm /var/lib/dpkg/updates/*
sudo apt-get update
sudo apt-get upgrade

The main reason should be that there are errors in the data in the/var/lib/dpkg/updates folder, resulting in errors in the software update program, so they have to be completely deleted. The sudo apt get update command will re-establish these data, use sudo apt get upgrade to update the details of the software installed in your computer, and update the software to the latest version according to the details of the software.

Reason guess:

The MySQL service is always turned on (it starts automatically after startup), so when it is turned on, an error will be reported when the command line is started

Solution:

Enter the command prompt in administrator mode and enter the following command to close the MySQL service

net stop mysql

So far, the problem has been solved. Entering mysqld — console again will open the MySQL service normally

[Solved] Error running ‘TomEE 10.0.121‘: The selected directory is not a TomEE hom

Today, I watched the video of Lao Du’s servlet and tried to start the Tomcat server after typing the code. I found this: error running ‘tomee 10.0.121 ‘: the selected directory is not a tomee Hom error.

Then I didn’t look at the error carefully. Subconsciously, I thought my Tomcat path was wrong. I looked it up and found that there was no problem

Finally, take a closer look at the good guy Tomcat created to tomcatee. No wonder it can’t be started.

Solution:

Just change back to normal Tomcat

Finally, click the servlet according to the old Du code
