How to install pamac?

[tk1107]

:: Checking for conflicts...
:: Checking for inner conflicts...
[Repo:8] python-bcrypt-3.2.0-3  python-gnupg-0.4.8-1  etc... (I put the etc here...there were more files)

Does this mean it is checking the files required for download for conflicts or there are actually conflicts in those files listed?

This seems like the regular procedure pacman goes through, there will always be the message that it's checking for conflicts. It's just informing you that it's checking, it doesn't seem to tell you it found any conflicts. If there were any, it would give you a warning like the one about gtk3 and gtk3-mobile you mentioned before.
If you can build the package successfully now with "makepkg -s", everything should be fine.

To get a better understanding of what is happening when building packages with a PKGBUILD (which then can be installed by pacman) you can read the Arch wiki articles about the AUR, PKGBUILD and makepkg. That helped me understand it much better.

The tip you gave me about editing the PKGBLD was helpful. I decided to try another "helper" called "yay". I installed yay successfully and it was so easy to do. I then used yay to install that missing dependency "libpamac-aur". It installed successfully. I then tried to install "pamac" with "yay", but yay asked me if I wanted to replace gtk3-mobile with gtk3. I aborted yay at that point. I went back to my original directory that we were working on and did "makepkg -si". Since I now had the missing dependency, it worked! I now have "pamac" and even "yay" installed. pamac and yay seemed to go right to the AUR repository and gave me alot of choices for downloading. The programmers that wrote these "helpers" were not messing around. It was more than I expected. I can use "yay", "pamac", and "pacman" to update my PinePhone from the terminal. After I updated with "yay", I checked it with pamac and pacman and it was still updated. I read that yay and pamac do the same thing, but in a different way.

With "yay" and "pamac", this PinePhone is now more of a cinch. I'm coming from one years worth of Ubuntu experience and Arch is a little different, but Arch runs better for my purposes on PinePhone than two other distributions I have tried. Each distro works differently for each person. I've used old Android phones I reflashed with two Linux distributions using the halium hardware abstraction layer. My PinePhone as it is now is where I want to be with Linux. I keep thanking everyone involved for the work with Linux distros on mobile phones.

I'll read those articles you pointed out. Thanks.
