Installation failed on Nexus 9 with Magisk and MicroG

kommserv commented 2 years ago

On first start of the app, superuser prompt displayed as expected and I granted rights "forever". The app then proceeded with "ACC installation...", and shortly thereafter I got the error message Installation failed with instructions to open a ticket.

I have copied the contents of the logs directory and uploaded it to my Nextcloud (note, I have extracted the contents of the tarball acc-logs-flounder.tar.gz).

I'm trying to repurpose an old tablet into a webcam (using Iriun) and extra screen real-estate, so it's more or less permanently connected to power via USB to computer, and I thought the battery could benefit from a set charging limit.

Nexus 9 running LineageOS 14.1-20211021-unofficial-flounder (Android 7.1.2) with Magisk 23.0, MicroG NoGoolag 2.9 with NanoDroid Patcher 23.1.2.x, TWRP 3.5.1_9-0, and Xposed framework 89 with XPrivacyLua 1.27. API level 25, kernel version 3.10.103 (razorloves), SELinux stats enforcing.

Any ideas on what could be going wrong?

VR-25 commented 2 years ago

Have you tried installing just the latest version of acc (the backend) from Magisk?

kommserv commented 2 years ago

I had not. Now I have tried it, but it did not work (details below). And thanks for the suggestion, I appreciate it! If you or anyone else has any other suggestions, even if after a while, I would be grateful.

Downloaded the latest zip from https://github.com/VR-25/acc/releases, installed it using Magisk:

(i) Rebooting is unnecessary
- acc commands may require the /dev/.vr25/acc/ prefix (e.g., /dev/.vr25/acc/acc -v) until system is rebooted.
- Daemon started.

I rebooted the tablet. Noted that there is no front-end app installed. I opened a terminal, and tried acc -v: not found. So I elevated the terminal to root and now it found ACC:

flounder:/ $ su
flounder:/ # acc -v

/sbin/acc: /data/adb/vr25/acc/batt-interface.sh[97]: .: /dev/.vr25/acc/.batt-interface.sh: No such file or directory

(i) This may take a minute or so...
(i) /data/adb/vr25/acc-data/logs/acc-logs-flounder.tar.gz

It seems any ACC command produces that same output above (I tried acc, accd,, acc -s and more). The folder in question exists and contains a bunch of files:

flounder:/ # ls -al /dev/.vr25/acc

Should I create this file /dev/.vr25/acc/.batt-interface.sh? Or is it missing because something went wrong with the installation? What if we simply create an empty file and see what happens:

flounder:/ # touch /dev/.vr25/acc/.batt-interface.sh
flounder:/ # acc -v
v2022.2.3 (202202030)
flounder:/ # accd,
(i) accd is not running
flounder:/ # accd
flounder:/ # accd,
(i) accd v2022.2.3 (202202030) is running (PID 12138)

Hm, well look at that! Without /dev/.vr25/acc/.batt-interface.sh, acc would not start at all, and neither would any front-end app. But simply creating the empty file seems to have resolved the problem?

Rebooted the tablet, opened terminal and checked ACC daemon again:

flounder:/ $ su
flounder:/ # accd,
/sbin/acc: /data/adb/vr25/acc/batt-interface.sh[97]: .: /dev/.vr25/acc/.batt-interface.sh: No such file or directory
(i) This may take a minute or so...
(i) /data/adb/vr25/acc-data/logs/acc-logs-flounder.tar.gz

Now this is very surprising! It seems some process has deleted the file has and now the ACC daemon is apparently broken again.

I went ahead and installed @CrazyBoyFeng's AccSettings frontend app v2022.1.17-dev, and after granting it superuser it fails to start acc (screenshot):

Selection_176

Now what if we apply our "fix" and make sure to start the ACC daemon in the terminal? Well, that seems to break the frontend app completely - it crashes and shows the Android pop-up "ACC Settings has stopped". Restarting the app does not help.

Just for completeness, I also tried to install AccA from F-droid again, but it failed to start with the same error message as originally reported.

This is on the same system as originally reported, except we are now using Magisk 24.1 (so no built-in Magisk modules repo, but as you can tell I worked around that).

CrazyBoyFeng commented 2 years ago

The last version of AccSettings had some issues with installing/updating acc, the fix will be released in the next version (but not soon). Until then, when using AccSettings, you can try to install it manually from the shell.
