Questions[k3b](ubuntu)

I recently upgraded from an obsolete machine and a no-longer-supported version of Ubuntu to a newer, faster machine with Ubuntu 18.04.4 LTS (Bionic Beaver, 64-bit). I am running MATE as my user interface (version 1.20.1).

On my old machine, burning audio CDs with K3B was virtually effortless. Whenever I hit "burn", the process usually went smoothly and successfully.

On my new machine with the new OS, I get the following error message:

"cdrecord has no permission to open the device Modify the device settings in K3B to solve this problem. "

Here is the debugging information:

System

Used versions

cdrecord: 1.1.11

cdrecord

cdrecord command:

/usr/bin/wodim -v gracetime=2 dev=/dev/sr0 speed=40 -sao driveropts=burnfree textfile=/tmp/k3b.oo7726 -useinfo -audio /tmp/k3b_audio_0_01.inf /tmp/k3b_audio_0_02.inf /tmp/k3b_audio_0_03.inf /tmp/k3b_audio_0_04.inf /tmp/k3b_audio_0_05.inf /tmp/k3b_audio_0_06.inf /tmp/k3b_audio_0_07.inf /tmp/k3b_audio_0_08.inf /tmp/k3b_audio_0_09.inf /tmp/k3b_audio_0_10.inf /tmp/k3b_audio_0_11.inf

I checked the permission settings in K3B, and everything looks the way it supposedly should. Still, I get the error message every time I try to burn a CD.

Furthermore, K3B (version 17.12.3) saves K3B project files in the form of ZIP files instead of the K3B files that the old version used. Consequently, when I try to open a K3B project file, it doesn't show up in the program's "open" command.

What we have here is either a very buggy program or something which can hopefully be easily and quickly solved.

Can anyone help me with this?

Installed K3B on Ubuntu 18.04 LTS. The emovix dependency, and/or optional programme is not installed. The emovix and/or movixmaker-2 packages are not in the 18.04 repos - is there a way to install this, or were they simply not packaged for 18.04?

I'm trying to copy CD tracks to my computer to put on my Android cellphone in lubuntu 18.10 i386 using default software. I couldn't figure out VLC (which wasn't properly playing the CD) so I opened K3b (first time using this, too).

I go into settings and it says "Unable to load KCDDB configuration module" in the CDDB tab. I searched Muon Package Manager for 'KCDDB' but there were no results. Searching 'K3b' shows everything installed except extra themes. How do I proceed?

I have this problem with k3b in 18.04 releases (Ubuntu, Kubuntu, KDE Neon...) In oldest releases I do not have this problem:

cdrecord has no permission to open the device
You may use K3bbsetup to solve this problem. 

I've searched online but I have not found any solution.

Can anybody help me?

When I open K3b, there is no menubar (that appears directly under the titlebar), only a toolbar.

How do I make the Menubar appear? I've tried tapping F10, Alt, Alt + F. How do I unhide the menubar?
