Fixed in fsleyes*; thanks.

Source URL, https://git.fmrib.ox.ac.uk/fsl/fsleyes/fsleyes/repository/archive.tar.gz?ref=${pkgver}, redirects towards a login page. This URL, https://git.fmrib.ox.ac.uk/fsl/fsleyes/fsleyes/-/archive/${pkgver}/${pkgname}-${pkgver}.tar.gz, allows the tar.gz file to be downloaded.

A similar issue appears to be affecting the fslpy package as well...

Thanks @tobac. Looks like reinstalling previous aur python packages (haphazardly installed them all) did the trick. There was also an issue about a missing "dataclasses" module. Reinstalling python-dataclasses fixed said issue.

@keiichiiownsu12: Yes, previous Python packages from the AUR need to be reinstalled, including fslpy, which (probably) causes your error.

Hello,

After a recent python update, the console has been displaying the following error when starting fsleyes (using X11):

Traceback (most recent call last):
  File "/usr/bin/fsleyes", line 33, in <module>
    sys.exit(load_entry_point('fsleyes==0.34.2', 'gui_scripts', 'fsleyes')())

ModuleNotFoundError: No module named 'fsl'

Thought the "fsl" module was found in nipype. Installed nipype via pip, but that did not solve anything. Should I maybe reinstall previous python packages?

Would it be possible to make a patch that creates a small shell script to launch fsleyes after setting the following environmental variable:

GDK_BACKEND=x11

This would then allow fsleyes to run under XWayland on Wayland desktop sessions.

Alternatively, some sort of alias might work:

alias fsleyes='GDK_BACKEND=x11 fsleyes'

EDIT: On second thoughts I'm not sure this is such a good idea. However, I'll leave my initial suggestions up here in case anyone is struggling to run this on Wayland.

Thanks for pointing these two issues out. Fixed in 0.34.2-2.

I also received the following error when trying to reinstall fsleyes:

==> ERROR: Failure while downloading https://git.fmrib.ox.ac.uk/uploads/-/system/group/avatar/85/icon_512x512.png
    Aborting...

Hi @tobac,

Just tried to run fsleyes for the first time since the update. It wouldn't launch, and threw this error when launched from the terminal:

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'certifi>=2020.06.20' distribution was not found and is required by matplotlib

I installed python-certifi via pacman, then all was well. You should probably add the package to the depends array of the PKGBUILD.
