Make sure to fetch the developers' signing key before building the package.

The official instructions are here. The link is also mentioned in the PKGBUILD.

If the site is blocked in your region, you'll have to work around it or trust me that this is what it says:

% gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org

which (as of 2024-06-26) should also show this fingerprint:

EF6E 286D DA85 EA2A 4BA7  DE68 4E2C 6E87 9329 8290

If your gpg says otherwise, you may have been fed garbage.

Tried both reinstalling coreutils and restart. There are my permissions for /usr/bin/cp:

.rwxr-xr-x@  133k root 20 Apr 10:58 <U+F086F> cp

edit: I'm thinking the "@" symbol in the permissions may be the perpetrator (don't see that symbol on my pi).

Maybe cp or one of the libraries it depends on is damaged on disk? Or RAM overclock pushed too far? I'd try rebooting and/or reinstalling coreutils.

Might just be a me issue, but I can't seem to install/update this package anymore. The below line keeps failing. Replaced my actual username with <user>.

Something else changed your $PATH (maybe ~/.profile, /etc/makepkg*, or /etc/profile.d). This package does not modify it in any way.

find: The current directory is included in the PATH environment variable, which is insecure in combination with the -execdir action of find.  Please remove the current directory from your $PATH (that is, remove ".", doubled colons, or leading or trailing colons)

sick of this shit package having to constantly manually intervene, why even have a fkn bin for, mullvad can fuck off

@tarball Could the PKGBUILD line #98 be changed from

find . -executable -execdir chmod --verbose a+x '{}' +

to

find . -perm -u=x -execdir chmod --verbose a+x '{}' +

The current approach with -executable will not work in some case (e.g., the BUILDDIR is located on an FS mounted with noexec).

hey @tarball, you're using an incorrect ffmpeg dependency for mullvad here. It should be ffmpeg4.4 and not ffmpeg. The latest ffmpeg is not compatible with firefox-based browser. See the correct firefox dependencies listed out in extra/firefox here: https://archlinux.org/packages/extra/x86_64/firefox/ Due to this incompatibility, video stutters in mullvad and you can check for proper compatibility when you navigate to about:support and look under "Media". All codecs should have software decoding support, which they won't unless your system has ffmpeg4.4

This program's license is considered to be a single license under MPL-2.0, not a dual license under MPL-2.0 and GPL-3.0-or-later.

The webpage linked from the Mullvad Browser LICENSE file states it is MPL-2.0, with no mention of GPL-3.0-or-later. Furthermore, the Readme file also only specifies MPL-2.0. Additionally, the source code headers only reference MPL, with no mention of GPL.

Does anybody know how to get this working on aarch64 systems?
