수년 전, 나는 우분투 폰이 큰 성공을 거두고 기존 플레이어들에 대한 훌륭한 라이벌이 될 것이라는 희망과 행복감에 휩싸인 사람들 중 한 명이었습니다. 나는 내 사이트의 독자들이 우분투 폰을 얻기 위해 시도할 수 있는 콘테스트를 진행하기도 했습니다. 간단히 말해서 한동안 전화를 사용했지만 다소 번거로운 것으로 판명되었고 잠시 후 Ubuntu 전화를 Android 전화로 바꿨습니다. 펌웨어 플래시가 완료되었습니다. 그러나 그럼에도 불구하고 Linux 리뷰의 일부로 연결을 테스트하기 위해 가끔 전원을 켜는 것 외에는 Aquaris를 심각한 용도로 사용하지 않았습니다. Android 운영 체제는 Ubuntu Phone보다 더 많은 기능을 제공하지만 오래된 이미지와 부진한 성능으로 인해 Aquaris는 모호해졌습니다. 하지만 잊혀지지는 않습니다.
시간이 지나면서 어떻게 더 좋아지고 세련되었는지, 어르신들에게 얼마나 유용한지, 픽셀과 코드 라인의 합을 뛰어넘는 매력과 영혼을 가지고 있는지 이따금씩 계속 생각했습니다. 운 좋게도 불과 며칠 전 공식 프로젝트가 취소된 이후 개발 및 유지 관리를 시작한 UBports 팀에서 새로운 업데이트인 Ubuntu Touch OTA-12를 발표했다는 발표를 보았습니다. 그래서 저는 Aquaris를 한 번 더 회전시키자고 생각했습니다.
모도르와 뒤로 펌웨어 플래시
OTA-12를 얻으려면 실행 중인(및 지원되는) Ubuntu 전화가 있어야 합니다. Android가 있는 경우 먼저 이전 Android 이미지를 설치하여 전화기를 "잠금 해제"한 다음 전화기를 OTA-12로 업그레이드해야 합니다. 후자는 공식 UBports 설치 소프트웨어로 편리하게 수행할 수 있습니다. 전자는 별도의 펌웨어 플래싱 유틸리티가 필요합니다.
내가 지난번에 뭘 했는지 기억나? SP Flash Tool을 사용해야 했습니다. 음, 도구입니다. 나는 여기서도 같은 일을 해야 했다. 공식 UBports 문서에는 내가 해야 할 일이 요약되어 있습니다. ROM 이미지를 가져오고, SP Flash Tool을 설치하고, 전화를 업그레이드하고, UBports Installer를 설정하고, 전화를 한 번 더 업그레이드하여 OTA-12로 업그레이드하는 것입니다.
여기에서 내 문제가 시작되었고... 모든 노력이 거의 사라졌습니다.
SP Flash Tool을 실행할 수 없습니다.
플래시, 오-오, 펌웨어의 구세주 ...
자세한 내용은 다루지 않겠지만 4년 전에 사실이었던 문제는 여전히 적용됩니다. SP Flash Tool은 다양한 종류의 데비안 또는 우분투에서 시작되지 않습니다. libQtGui.so.4 라이브러리의 오류로 인해 누락된 libpng와 segfaults 사이를 번갈아 가며 불평했습니다.
./flash_tool:공유 라이브러리를 로드하는 동안 오류가 발생했습니다. libpng12.so.0:공유 개체 파일을 열 수 없습니다:해당 파일 또는 디렉터리가 없습니다.
sudo ./flash_tool.sh
부동 소수점 예외(코어 덤프)
[ 110.640840] traps:flash_tool[2778] trap split error ip:7f3ae6ff7568 sp:7ffcc1edc5c0 error:0 in libQtGui.so.4[7f3ae6ada000+b39000]
여러 가지 방법으로 문제를 해결하려고 노력했습니다. 나는 나중에 M10 태블릿과 E4.5로 나에게 도움이 되는 것을 시도했는데, 그것은 libpng deb를 수동으로 설치하는 것이었다. 작동하지 않았습니다. 패키지를 전혀 설치할 수 없습니다.
그런 다음 라이브러리를 추출하고 LD_LIBRARY_PATH에 추가했습니다. - btw, 플래시 유틸리티를 실행하는 flash_tool.sh 스크립트는 실제 소프트웨어에 대한 환경을 설정하는 쉘 스크립트입니다. 그러나 이것도 도움이 되지 않았습니다.
dpkg -x libpng12-0_1.2.54-1ubuntu1.1_amd64.deb "somepath"/libpng12
...
LD_LIBRARY_PATH=$dirname:$dirname/lib:"add here the libpng12 path"
export LD_LIBRARY_PATH
...
I tried forcing SP Flash Tool to use a different version of Qt libraries, except:
./flash_tool:symbol lookup error:lib/libQtGui.so.4:undefined symbol:_ZN27QEventDispatcherUNIXPrivate16initThreadWakeUpEv
In the end, I rebooted into Fedora 32, and here, it ran without any issues.
UBports installer
Now, I could finally proceed. This was a fairly straightforward process. The biggest issue was to get to the Aquaris bootloader - the installer instructions aren't correct. You need to press the Volume Down and power button until the phone cycles (red light turns on and off), and then you need to release only the power button. And the arrow animations while the firmware image is being written to the device are annoying - you can turn them off.
The instructions are not correct.
Finally, presenting OTA-12
My Aquaris booted just fine, and after about a minute or two, I had the Ubuntu Touch first-run setup load. I created my account (just a name, no email or number needed), and that's pretty much that. Time to explore.
The new Ubuntu Touch is based on 16.04 (Xenial). Visually, things are similar to the old version, but then, there are also some fresh touches and improvements. Most notably, Unity8 work. The UI is also more responsive than it was in the past, and it's also significantly faster than Android on Aquaris E4.5. As this is a low-end device, every little bit counts.
I have to say the interface is quite pleasant. Less rounded than it was - which is a good thing. More square angles, more stackenblochen. The system settings cover all the basics, but if you're used to Android, things will look super simple and bare. The one thing that is missing - device encryption. The rest is there, easy and simple to access and use.
Store and applications
Now, the one cardinal issue that OTA-12 cannot solve is the lack of support for the ecosystem. There just aren't enough high-profile, mainstream applications available to make this community-supported Ubuntu Phone relevant in the modern world. The browser has been revamped, so it does the job well, and the utilities that are bundled by default also function well. Again, you get a broad improvement across the entire spectrum. But this just isn't enough to dent the need pyramid of the general user.
I tried searching for something that I'd easily identify - and there really wasn't much. For instance, Firefox or VLC aren't there. For navigation, you have Pure Maps and uNav, but these aren't necessarily your first choice. This is a huge limiting factor, and it remains without a straightforward answer in 2020. Then again, I knew this when I started this fun endeavor. This was all meant to be a moment of simple, innocent joy.
Music and video
I loaded a bunch of HD videos on Youtube - no issues. Music, pretty and solid. No issues.
Modern connectivity
You're not entirely locked in the past. You can hook up various accounts into your Ubuntu Touch system, including Evernote, Nextcloud, generic calDAV (not sure what this is), ownCloud, and Google. This isn't an overwhelming set, but it's not bad either. You can also import contacts from a Google account. Now, if you recall my contact import saga from Lumia 950 to Motorola One Zoom, then you will realize that OTA-12 offers a fairly reasonable set here.
Libertine
OTA-12 comes with Libertine, a container-based solution that lets you run standard Armhf-based software from Xenial repositories, intended for the ordinary Ubuntu desktop. I thought this would be a good way to replenish my app stock, and work around the dearth of software in OpenStore.
Unfortunately, this didn't work - my greatest disappointment throughout this review. I tried to install VLC, and after a few minutes, the installation failed. Firefox setup would start, fail and then start again, in a loop. In the end, I had to open the terminal application and manually delete the containers. I got no app installed or configured. If this ever works reliably, robustly, it would be an awesome thing.
결론
I'm happy with my little experiment, even if it serves no higher purpose. Now, on my M10 tablet, I won't repeat the exercise. It's a fairly capable device, and there, Android 6 does a pretty good job - a marked improvement over Android 5 that was on Aquaris E4.5. Indeed, Android has significantly improved over time. But on the phone, OTA-12 works quite well, and offers a fast if limited experience. But for novelty sake, I'm going to take this as far as it goes, either the UBports project or the lifespan of the device.
The community-supported continuation of the Ubuntu Phone effort - UBports Ubuntu Touch - is a commendable project. Given its resources, it manages to deliver a fairly robust and fun product, with OTA-12 as its latest incarnation. Solid, usable - to an extent, but also secure, updated and with solid privacy. If you need a basic smartphone, this is a solution that offers a reasonable compromise. I've never really expected to be using Ubuntu Touch again, but now I'm glad I did this, if only to see how far one's passion can stretch. But on a serious, emotionless note, really, if you don't need much, if you're not hooked into social media, and if your hardware supports the OTA-12 image, you might want to give this a try. If anything, it's more mature than it ever was, and in the privacy-focused world, it makes perfect sense. From Nostalgia Avenue, Dedoimedo out.
