Pencil Project installation Issue on ubuntu 18.04 LTS

[waynelwh]

• Operating system:Ubuntu 18.04 LTS
• Pencil version:3.0.4 The pencil project seems not available on ubuntu 18.04 LTS. I have download the Pencil_3.0.4_amd64.deb and tried to install it but it didn't work. I have only got a icon in the "Show Application" and there is nothing when I clicked it. Also, when I tried to find the related software in "Ubuntu Software", I couldn't find it in "installed". I therefore downloaded and installed it in Windows 10 and everything is fine.

Go the the directory that .deb file exists in it and try sudo apt install ./Pencil_3.0.4_amd64.deb && sudo apt install -f I just installed it using apt today

Thanks for your reply! I have tried your way to install but it doesn't have any difference. The software icon is in "Show Application" but it cannot be opened like it is just a icon there. Also, it still cannot be found in "installed" in "Ubuntu Software". Apart from this, I previously got problem when I tried opening setting since it would be crashed and going back to the login page. I suspect it may be caused by removing the pencil project but I am not so sure about this since the problem was solved by downloading the drivers(fyi: https://ubuntuforums.org/showthread.php?t=2391819).

I resolved my problem executing the commando to install a missing library packages. Try it:

sudo apt install libgconf-2-4

I installed latest version ofpencil from deb file,

# dpkg -i pencil_3.1.0.ga_amd64.deb 
Selecting previously unselected package pencil.
(Reading database ... 430013 files and directories currently installed.)
Preparing to unpack pencil_3.1.0.ga_amd64.deb ...
Unpacking pencil (3.1.0.ga) ...

But nothing happen when i run it from Application launcher menu.

I also try to run it from the command line:

$ pencil

Hey I couldn't start the software either, even after reinstalling. Then I tried to debug the software using strace, and Pencil magically started. And it starts seemingly normally after that. Not sure if it is just my laptop/system but do try HAHAHAHA.
