@lduboeuf Ok, thank you for your answer I will look into this ..

Hi,

with the current clickable framework, is it still possible to write an app for 16.04? Are there some examples?

Thank you very much for any answer

@etdoughe Thank you for the link. I now can transfer data via usb using the recovery mode ;). Although I would prefer a OTA-26 release which fixes the usb issue ... or at least a patch or something, but you can't have everything ;).

@kugiigi In our local network at home, I always use the ssh connection to the phone (I have debian bookworm on my PC). The first time I noticed the problem after my update to OTA-25 was when I wanted to write a small clickable app for starting and stopping ssh: I found a tutorial to write clickable apps and there were promoted two ways to deploy the app, via usb or via ssh. I decided to use usb and voila, I noticed the problem ;).

@Moem Hi, thanks for your post. Oh ok, what phones do you suggest for Focal? Ups I think I can answer the question: In the devices list https://devices.ubuntu-touch.io/device/bonito/ one finds the release channel information ;). So f.e. a Google Pixel 3a would do the job

@etdoughe I have the same problem (I have a Samsung S3 Neo with 16.04 on it). The moment I updated to OTA 25 no data transfer was possible anymore. Since I can't update to Focal, the S3 Neo hasn't been ported yet (or never will be ;)), I have a problem...

@kugiigi Thanks again for answering. Ok, besides f.e. a pine phone, I find among the promoted phones also the Nexus 5. So this could be a candidate for me ;). But phones becomming more like PCs with respect to updates und more general with respect to hardware specifications/standards etc. would be a nice thing.

@kugiigi Thank you again for answering. My next phone will definitely be a pine phone or something similar. These phones seem to be less complicated and may be more like PCs, presumably here the update process is also less complicated ;).
ps ..: The main reason why I made this post was that the moment I upgraded to OTA-25, my PC (OS: debian bookworm) started to not recognize the device anymore via usb. This issue seems to be known: https://forums.ubports.com/topic/9661/no-usb-data-transfer-on-pixel-3a/13?_=1711885273676
An upgrade to Focal seems to fix the issue.

@kugiigi Thank you for your answer. I thought that during an update, the older kernel belonging to my 16.04/S3 would be automatically replaced by the kernel for 20.04/S3 which I thought is automatically derived from the kernel belonging to 16.04/S3. But this seems to be more complicated ;). So I should buy either a newer device, or I should learn how to port ;), or both ...

Hi,

I have 16.04 installed on my Samsung gt i9301i. Has anyone successfully updated 16.04 to 20.04 yet? Is this in principle possible?
@Ubuntu Touch Team: This is a nice operating system, thanks for your work!
