privoxy: error: The given value 'privoxy' does not match group entry

[allamistakeo19@…]

Hi,

After installing Yosemite, I re-installed MacPorts, but now I get the following:

--->  Configuring privoxy
Error: Failed to configure privoxy, consult /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_privoxy/privoxy/work/privoxy-3.0.21-stable/config.log
Error: org.macports.configure for port privoxy returned: configure failure: command execution failed
Please see the log file for port privoxy for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_privoxy/privoxy/main.log
Error: Unable to upgrade port: 1

See log attached.

It looks like the error is:

configure:3890: checking for user
configure:3900: result: privoxy
configure:3928: checking for group
configure:3938: result: privoxy
configure:3945: error: The given value 'privoxy' does not match group entry

So, what is the group assigned to the provixy user on your system?

[allamistakeo19@…]

$ id privoxy
uid=500(privoxy) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),405(com.apple.sharepoint.group.4),403(com.apple.sharepoint.group.2),402(com.apple.sharepoint.group.1),404(com.apple.sharepoint.group.3),100(_lpoperator)

By the way, I have also just noticed that the group privoxy is now displayed in the Users and Groups section of the System Preferences. I don't remember it being the case in Mavericks.

I solved it by resetting the main gid of the user privoxy using the command line I found there: ​http://apple.stackexchange.com/questions/81543/how-do-i-change-the-primary-group-for-an-existing-user

Has duplicate #55864.

We also see this problem on at least one of the buildbot machines:

The problem is really in the primary group of user privoxy.

localhost:~ petr$ id privoxy
uid=504(privoxy) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),702(com.apple.sharepoint.group.2),100(_lpoperator),703(com.apple.sharepoint.group.3)

The group should be privoxy instead of staff.

The group privoxy exists on my system and has ID 504.

This solved the configure issue:

localhost:~ petr$ sudo dscl . -create /Users/privoxy PrimaryGroupID 504
localhost:~ petr$ id privoxy                                           
uid=504(privoxy) gid=504(privoxy) groups=504(privoxy),12(everyone),20(staff),61(localaccounts),702(com.apple.sharepoint.group.2),100(_lpoperator),703(com.apple.sharepoint.group.3)

What I don't understand is when the privoxy user and group is created and by whom. It must be dome by MacPorts even before running the configure script otherwise the privoxy could never be installed for the first time. Hmm…

Thank you!

I’ve also seen this a couple times. I don’t have good solution except to delete the privoxy user and privoxy group using dscl or Directory Utility.app, rerun port install privoxy, which re-creates this user and group, and check permissions to make sure that the automatically re-created user and group have the same uid and gid. If not, apply chown and chgrp appropriately.

This shouldn’t happen.

Please see ​https://github.com/macports/macports-ports/pull/16221

I still don't understand the MacPorts-based cause of the issue (I suspect it has something to do with the exec -ignorestderr $dscl flag in ​https://github.com/macports/macports-base/blob/master/src/port1.0/portutil.tcl), but at least this PR fixes the issue if it arises.
