Personally I like GNOME guidelines

I don't know of any besides for material 3 and GNOME

1. Plug in the dvd

2. Run lsblk to see if it got detected

3. Run dd if=/dev/cdrom of=dvd.dvd status=progress

4. You can now play the ripped dvd using mpv: mpv dvd://0/dvd.dvd

If you need to get rid of digital restrictions management, you can try this guide

So I am trying to port postmarketos, I have gotten very far (everything has compiled) but there is an issue during pmbootstrap install

Before you ask I have asked Matrix/IRC

I noticed my SoC has mainline support so I'm mainlining it

Phone specs:

• Samsung Galaxy A127F
• Exynos 850 SoC
• stock bootloader

Logs:

• pmbootstrap zap; pmbootstrap -v install
  • shortened
  • full

Files used:

• device-samsung-a12
  • deviceinfo
  • APKBUILD
• linux-samsung-a12
  • APKBUILD
  • config-samsung-a12.aarch64
  • enable_HAVE_KERNEL_GZIP.patch

What I think is happening:

• mkbootimg is failing for some reason

What I think can fix it:

• Disabling it. This wiki page says:

  " generate_bootimg | Set this to true for fastboot device, so the mkinitfs command will generate a boot.img file after creating the initfs. Add mkbootimg as dependency to your device's APKBUILD! "

  I don't know if a phone using samsungs download mode counts as a "fastboot device" I have tried disabling it but heimdall then stopped at 6% I followed the advice of the wiki but then heimdall got stuck at 27%

• Adding more arguments. The error is error: not enough arguments '/tmp/mkinitfs1981624154/boot.img' so just add the arguments? The problem is I don't know which ones. According to the wiki I could use bootimg_custom_args to add custom arguments, but which custom arguments? And where are the files arguments like --kernel should point to?

Please remind me if I forgot to mention anything and I will happily edit my post :D

Edit: I would just like to say thanks to everyone who has helped me on previous issues and anyone who helps me on any other issue (including this one)

Phone used for testing (not that I got that far): Samsung Galaxy A127F

Kernel source code used:

1. Search for "SM-A127F_CIS_13_Opensource.zip" from samsungs website
2. Move it to somewhere like ~/projects/postmarketos/stock/SM-A127F_CIS_13_Opensource.zip (referred to as $stock from now on)
3. unzip $stock using unzip $stock command
4. there should now be a "Kernel.tar.gz" file. Make a new directory called "Kernel" (the path to this directory would be called $kernel from now on.) Move Kernel.tar.gz to $kernel. Extract $kernel by running tar -xf Kernel.tar.gz

As you can guess I couldn't find the kernel in a git repo so I followed the wikis advice of running pmbootstrap samsung-a12 --src=/$kernel

[15:44:27] ERROR: Could not find aport for package: samsung-a12
[15:44:27] See also: <https://postmarketos.org/troubleshooting>
Run 'pmbootstrap log' for details.

well that seems interesting

I didn't find any reference to the error message in the wiki and while I did find a promising google result (proxied through a metasearch engine of course) it was a reddit thread that wasn't archived by the wayback machine

Why this might have happened:

• the wiki said that if you didn't install pmbootstrap through git the places would change. I didn't install it through git but it might be assuming I did
• the wiki never said if I had to change anything in "linux-samsung-a12/APKBUILD", so I assumed I didn't need to change anything, maybe I did?
