Trying to install protonmail bridge downloaded pkgbuild file but not sure how to use

[MikeHunt]

Hi
So Im trying to use my protonmail account on thunderbird and when i looked through the protonmail support page it directed me to download a PKGBUILD file I couldnt figure out how to use this file so i searched the forum and came across a post about something called autogit which seems to facillitate the use of such files. My question is how do I use this tool. Im going to post the file I downloaded if its of any use

# Maintainer: Proton Technologies AG (ProtonMail Bridge developers) <bridge@protonmail.ch>

pkgname=$_pkgname-bin

package() {
  tar -xzC "$pkgdir" -f data.tar.gz
  rm -rf "$pkgdir/opt"
}

So how do I use this file?

[winnie]

It exists in the AUR: AUR (en) - protonmail-bridge

Use Pamac (“Add/Remove Software”) to install it. Make sure to enable AUR support in its preferences.

As long as everything looks legit to you in the PKGBUILD, such as the “source” and build/package instructions, as well as other users’ comments, you should be fine.

i used pamac build protonmail-bridge and it seemed to work however the package maintainer name was slightly different but Im not sure if thats because the pkgbuild file was a more general description or whatever. However I havent come across any comments on the AUR claiming that its malicious in nature and I emailed protonmail support asking about whether or not this was the authorized package. Should I just reinstall manjaro?

@MikeHunt

Should I just reinstall manjaro?

Why? Sounds like everything went smoothly.

The PKGBUILD on the AUR is formatted correctly and has correct package and build instructions (used by Pamac, makepkg, etc).

The sources appear to originate from Proton’s official GitHub.

I don’t understand what the problem or concern is?

yeah Im just a bit irrationally paranoid. I have to say the software is not the best. A staggering drop in performance. but thanks for the help
