Morning everyone,
After years of lurking I'm taking the plunge to at least explore how to write the apps that I miss when I'm using Ubuntu Touch. I have the Aquaris E4.5 and M10 HD Tablet, and I would like to use them more than I do so.

I'm an experienced developer, and I've been working in Linux and other Unix-like environments since the 90s, so I didn't think that it would be particularly difficult to get up and running, particularly as clickable seems to do the heavy lifting.

However, whichever way I've turned I've run into trouble, and I've not been able to get going. Firstly I thought this could be a good opportunity to learn Go, so I've build the template with that. When I call clickable desktop I get this response

Successfully built package in './gotest.fats.am_0.0.1_amd64.click'.
non-network local connections being added to access control list
Mounting device home to /home/sjp/.clickable/home
docker: Error response from daemon: error while creating mount source path '/gopath/path/home/sjp': mkdir /gopath: read-only file system.
sjp@orac:~/MyWorkspace/GoTest$ echo $GOPATH
/home/sjp

OK, I thought, I'll switch to C++. I found @CiberSheep's video at https://www.youtube.com/watch?v=JBMGhq-xT6c and started to follow that. He has a nice and simple first run through the creation process, but when I try to follow it I get
non-network local connections being added to access control list

Mounting device home to /home/sjp/.clickable/home
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-phablet'
qt.qpa.screen: QXcbConnection: Could not connect to display :0
Could not connect to any X display.
sjp@orac:~/MyWorkspace/CloudMusic$ echo $DISPLAY
:0

Finally, I'm also trying to target my E4.5. I've checked that it is in developer mode, and when I plug it in, Ubuntu detects it and mounts it (is this the problem?), but adb won't have any of it

sjp@orac:~/MyWorkspace/CloudMusic$ adb devices -l
List of devices attached
JU002975               unauthorized usb:1-1 transport_id:2

Any help in getting any further with any of these issues is gratefully received!

Thanks
Sam

Thanks @AppLee I'll install that and give it a go. I suspect that what I want is more specialised than this, but I'll look into it and see if it can help shape my thinking. I'm happy to build something that syncs with the standard player, my original intention (back in the day) was to do something fancy with the music scope.

@3arn0wl the thing I miss the most on Ubuntu Touch is not having a cloud-based player. I've spent years building my collection* on OneDrive (I know, don't start) and I use an app called CloudPlayer on Android (https://play.google.com/store/apps/details?id=com.doubleTwist.cloudPlayerPro) I even pay for the premium version. It allows me to sync albums from my OneDrive to the local machine for my commute. I'd like to replicate this on Ubuntu Touch.

@arubislander of course, but I have more free time tomorrow and Friday than I do today

*by 'collection' I mostly mean Doctor Who stories from Big Finish

@arubislander thanks, I'm GMT/UCT. In the meantime I think that I'm going to start on my app in QtCreator and see if I can start writing code that I can port to UT later.

I might be due a full wipe-and-reinstall with 20.04 LTS, so it might be better to wait for that and start with a guaranteed clean machine rather than a laptop I've been using for three years (on 19.10 now)

@arubislander Thanks, I've got 'Ubuntu' selected rather than 'Ubuntu on Wayland' (I'd never noticed the option before!).

@arubislander Just my desktop session, I don't have anything else running, and I'm just running this on my laptop, I've not created a VM or anything that might be headless.

Thanks @arubislander & @poVoq . I'm running Ubuntu 19.10. I installed clickable 6.10.0 from the PPA, which seems to be the latest version.

Rebooted, but same errors.

@DansLeRuSH Hi Frank, I know what you mean about being pissed off. I was very cross at the time, but I guess I understand that whole of the rest of the Ubuntu product line was being held up by UT and they needed to move on.
uNav is great for Japan mapping data, much better than Google. I remember I took Maps.me with me last time, but I'll take uNav next time.

Ha yes, I pointed it out to my son last weekend. We'd watched Micro Men previously so he knew who they were
