After apt-get upgrade -terminal frozen

[ozstar]

Apt-get update was fine but after apt-get upgrade -terminal frozen ay mysql message about log.

Told another script is locking it.

root@zorin162-VirtualBox:~# apt-get upgrade
E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 59302 (apt-get)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

root@zorin162-VirtualBox:~# rm /var/lib/dpkg/lock
root@zorin162-VirtualBox:~# dpkg --configure --pending
dpkg: error: dpkg frontend lock is locked by another process

What to do?

If another process is using updates you can't have two sessions of updates at once. For example, if you start Software Updater off you can't install packages via Synaptic, as dpkg is having to run to install the updates - this is the only time this happens - you can't have to instances of 'root' elevation at once.

Something else is running an update, most likely the built in software updater.

you can find out where it says "it is held by process 59302"

in terminal type

top -p 59302

Just change the process number by what ever one is currently showing as an error

it will show you the process information and on the far right the command being run - here is an example of a process

Thank you guys. I thought I waited but it took so long, 15 mins.
I like the check too, thanks.

All good now anyway.

how to stop it? specially the apt-get

[seanhinkley]

try

killall apt-get

if that fails, get the PID
and

kill -SIGKILL pid
