dpkg：错误：dpkg 状态数据库被另一个进程锁定

Question

Delete the updates with: cd /var/lib/dpkg/updates sudo rm *

Tried to update and upgrade: sudo apt update sudo apt upgrade

Still it says that: E: Could not get lock /var/lib/dpkg/lock This means that some program is blocking the system or installing a new software.

Check if any programs is locking dpkg file:

ps aux | grep -i apt

try to see which are existing locks

sudo lsof /var/lib/dpkg/lock sudo lsof /var/lib/apt/lists/lock sudo lsof /var/cache/apt/archives/lock

Try to delete them using:

sudo rm /var/lib/apt/lists/lock sudo rm /var/cache/apt/archives/lock sudo rm /var/lib/dpkg/lock Try again:

sudo dpkg --configure -a It should work.

Try again to installing with:

sudo apt update sudo apt upgrade This should resume the process and keep everything stable.

this way it resolved my issue of dbpkg is locked

Answer 1

List locks using:

lsof /var/lib/dpkg/lock

Then check if any process is running:

ps cax | grep PID

If any process is running kill it:

kill PID

#wait kill PID

ps cax | grep PID

Remove the lock file:

sudo rm /var/lib/dpkg/lock

Fix dpkg:

sudo dpkg --configure -a

This way it resolved the issue.

Answer 2

This issue is fixed for me by making ensure there should be no installation process running. I was installing vscode by dpkg command. also installing via terminal. So I stopped the terminal installation process of vs code.
