DPKG Was Interrupted, You Must Manually Run dpkg –configure -a to correct the problem

Sharing is caring!

Now I share Ubuntu server upgrade command error like dpkg was interrupted, you must manually run dpkg –configure -a to correct the problem. So I remove this error using below method.

When run apt upgrade so I see below error.

$ apt upgrade

Error :

dpkg was interrupted, you must manually run ‘dpkg –configure -a’ to correct the problem

So I run dpkg –configure -a this command then again see below error.

$ dpkg –configure -a

Error:

dpkg: error: parsing file ‘/var/lib/dpkg/updates/0004’ near line 0
newline in field name ‘#padding’

Solution : #01

rm /var/lib/dpkg/updates/000*
apt-get clean
apt-get update
apt-get install ttf-mscorefonts-installer
dpkg --configure -a
apt upgrade -y

Sometime fix package needed like below command.

apt --fix-broken install
apt-get update

Now install another package using apt command.

Error below:

packages can be upgraded. Run ‘apt list –upgradable’ to see them.
E: Could not get lock /var/lib/dpkg/lock-frontend – open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

Solution :#02

lsof /var/lib/dpkg/lock
lsof /var/lib/apt/lists/lock
lsof /var/cache/apt/archives/lock
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
dpkg --configure -a
lsof /var/lib/dpkg/lock-frontend
sudo rm /var/lib/dpkg/lock-frontend
sudo dpkg --configure -a
apt upgrade -y

Enjoy it 🙂
