Ubuntu Software - jimalexander - 09-18-2018

Good afternoon!

I apologize if this has been asked already, i searched and came up with nothing.

I migrated to Lite because Ubuntu LTS was slowing down on my laptop. HP, 8 gig RAM and 2.2gHz core i3. I need to install software that was in the Ubuntu software center (QUCS circuit simulator to be specific) but I can't find it through the synaptic manager or apt-get.

Is there any way to install this software, since Lite is based on Ubuntu?

Thanks all!

First, you need to add the repository:

Code:
$ sudo add-apt-repository ppa:fransschreuder1/qucs

Then, update apt-get database
Code:
$ sudo apt-get update

and finally install QUCS
Code:
$ sudo apt-get install qucs

Hope this helps!  Smile

Thanks for the help.

Everything works fine until i get to the installation, which throws:

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Thanks,J

Hello jimalexander,
can you try rebooting then installation.

After the reboot if it still will not install there are other ways to try for this error, to remove the lock.

This often happens when there's a still running instance of apt being stopped before, i.e you stopped it with Ctrl + C. I've also faced this problem and this is the way I know how to fix it, and if you google for it that would be the first result you'll get.

In a terminal type
Code:
$ sudo rm /var/lib/dpkg/lock
and then
Code:
$ sudo dpkg --configure -a
after that run
Code:
$ sudo apt-get update
and then
Code:
$ sudo apt-get install qucs

Hope this helps! Smile
