Environment variable LOGNAME or USER does not correspond to effective user id

[tompscanlan]

Overview of the Issue

Running packer on a host indirectly. I'm seeing a warning that looks like it is causing a parsing error. when doing a VBoxManage --version.

This is the error:

Error reading version for guest additions download: No version found: WARNING: Environment variable LOGNAME or USER does not correspond to effective user id. 7.0.16r162802

Reproduction Steps

I'm only able reproduce using this indirect call to packer through another tool. Error seems to be here:

packer-plugin-virtualbox/builder/virtualbox/common/driver_4_2.go

Line 321 in 54c5a24

versionRe := regexp.MustCompile("^([.0-9]+)(?:_(?:RC|OSEr)[0-9]+)?")

when a string is prepended to the version.

Plugin and Packer version

Opened ticket upstream, but we could be defensive with a slightly tighter regex.

Hi there @tompscanlan this is not a bug in the plugin, as the returned version from VBoxManage --version is returning "Environment variable LOGNAME or USER does not correspond to effective user id\n7.0.16r162802" which is indeed not a validated version. The VBoxManage command is returning this warning because the invocation of Packer is executed by a user whose name does not match the logged-in user $LOGNAME. Can you shed some light on where you are invoking Packer and how?

Are you invoking the script via a crontab?

If you are invoking Packer from a crontab, specify a username or set the user to $LOGNAME via env USER=$LOGNAME in the crontab entry.

[tompscanlan]

I forget details now, but invocation was not via crontab, but was indirect like Makefile -> scriptA.sh -> scriptB.sh which may have switched users.

The real issue is upstream I believe, My ask here is to improve the error message. I dug for a bit and could have saved time with a better error. If it doesn't make sense to change, then no worries, just close.

Hi,
I see this happening while running VirtualBox >= 7.0.16 (official and rpmfusion) inside Docker. While on 7.0.14 everything was working but now Packer (tested with 1.10.3 and 1.11.2) builds break with the aforementioned message:

On the host side everything's as expected:

[user@localhost]$ vboxmanage --version
7.1.0_rpmfusionr164728

[ifurther]

The message is this
WARNING: Environment variable LOGNAME or USER does not correspond to effective user id.\n7.1.0_rpmfusionr164728
Maybe this line is broken
