`nobody` can't build Rust/Java packages

I think this problem might be related to how aura separates build process from root and "my" user. Failure that I have is related to a HOME directory of nobody that is set to / and missing rust default toolchain. error: could not create home directory: '/.rustup'

[fosskers]

How are you invoking the build? What's the exact command that you're running?

I'm experiencing the same issue with other Rust packages from AUR.

$ aura -Akxua
...
error: could not create home directory: '/.rustup': Permission denied (os error 13)

If so, this seems to cause even more problems, e.g. with some other packages:

Verifying source file signatures with gpg...
    dropbox-lnx.x86_64-205.4.5765.tar.gz ... SIGNATURE NOT FOUND
FAILED
==> ERROR: One or more PGP signatures could not be verified!

@mkoloberdin To confirm: you're running Aura as the root user and without invoking sudo manually, yeah?

[CapSel]

I run aura with sudo, always. It does not work with root account - like after sudo -s or su.

[fosskers]

Running aura with sudo is no longer necessary as of Aura 4. It should work as-is for root now as well. @CapSel , can you try rebuilding the original Rust package you were trying to build? Note that Aura is also a Rust package and can build itself without issue.

Omitting sudo for aura 4.0.3 also solved these issues for me when building the packages firefox-tridactyl-native and amdgpu-top with sudo aura -Aua:

oserrors.nim(92)         raiseOSError

    Error:  Permission denied
        ... Additional info: /.nimble/
==> ERROR: A failure occurred in build().
    Aborting...
aura :: Package failed to build, citing:

  makepkg failed.

and

error: could not create home directory: '/.rustup': Permission denied (os error 13)
==> ERROR: A failure occurred in prepare().
    Aborting...
aura :: Package failed to build, citing:

  makepkg failed.

I assume users of aura are used to calling sudo aura ... from the time before the transition from Haskell to Rust. I appreciate that the new aura apparently doesn't need root permissions anymore.

I posted that it's no longer necessary across every sensible doc location I can think of, but old habits are probably hard to break. At least these Issues will serve as a record for anyone else who runs into the same thing.

Closing, as running Aura without sudo avoids the issue.

I've got similar problem with su instead of sudo when compiling sourcetrail:

[ERROR] Could not create local repository at /.m2/repository -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

Same error with sudo. Is it related?

[fosskers]

What was the command you used to run Aura?

[CapSel]

aura -Aux for upgrade, as I already had sourcetrail installed before.

[fosskers]

And if it's trying to create /.m2/, I suppose you're running as the root user (thus dropping down to nobody)?

[CapSel]

Same error happens when I this command as root and with sudo.

So as mentioned with ~/.cargo/ above, it seems that certain languages need temporary folders in which to put their dependencies during the build process, and by default they put them under ~/. When Aura is used as root, it drops down to nobody for building. However, nobody has no $HOME, so it attempts to write to / which it has no permission to do.
