Today, I found out that I have empty /android/persist folder. Could it bring about my problems with the cellular? Do I catch correctly, that /persist partition is responsible for sensors and carrier network etc on Android? And is it important to have some files in that folder for the same reason in Ubuntu touch? Other sensors works perfectly, I have no trouble with wi-fi adapter or data. But could be the clue missing files in that folder?

Thank you. It's clear to me now.

Is it normal that I can see in Channel settings dev and rc channel twice? And stable channel only once. Is there some difference between them? I am on stable (Ubuntu 16.04 OTA-24) but I am confused why I can choose the other channels twice. Am I missing second stable channel?

@jonius Thanks for your answer. But I have a little bit different problem. I have a bike GPX trace. It goes from starting point though the point A and the point B to my destination point. There is a official cycle way between the points A and B. But Pure maps don't know about the cycle way. So, counting trace by GPX smart stops at the point A. I am looking for some tool that can tell to Pure maps: "You can connect these two point, there is a way".

Hello.

Could anyone help with gpx track in Puremaps? I have two points and I would like to connect them in Puremaps by using GPX smart.
Point A: Latitude: 49,842277
Longitude: 14,581527
Point B: Latitude: 49,842333
Longitude: 14,581694

There is a way between the points, but track counting stops at point A. GPX works correctly, it shows all the track, but there are no instructions. I’d like to use GPX smart but it can’t count all the track and shows that the destination is point A. But the track continues though point B.

@arubislander Do you mean updates of applications? Yes, I receive these updates. I have Axolotl 1.0.7, Dekko 2 0.3.3 and uRadio 2.2.3. And UT Tweak Tool tells that my distro is Ubuntu 16.04.7 LTS.
According to Lakotaubp's post could reinstalling UT help me?

@arubislander I am on devel - downloaded from this site

Hello. I have some troubles with Dekko2, Axolotl and uRadio. These apps have no connection to internet. The problem has started on October. I have e-mail till 29thSemptember on Dekko2. But my device (Sony Xperia 10) could reach the internet, because I can use Teleports (or Telegram), Morph browser or OpenStore without any restrictions. What should I have to look for on logs files to find out what is wrong?

@applee Exactly. I am looking for correct command.

Is it a chance to change wallpaper in terminal? I have tried gsetting set org.gnome.desktop.background picture-uri 'path/to/picture.jpg'
but it did not work.
