Some users invisible/unusable

[RoyK]

Impact:
On some architectures (powerpc, arm*), adding an user account empty the user list from the users panel and lightdm

Test Case:
On powerpc or arm*
- open the users panel
- add an account
- look at the users list in lightdm or in the user panel

before the fix only one user would be left listed

Regression potential:
users could be incorrectly added or listed

---

On Ubuntu 12.04 beta for ARM, OMAP4, on a pandaboard, creating a user from User Accounts (system settings) creates user and it looks ok, but only the latest user created is visible in login screen and in further work in User Accounts. I set the password using 'passwd user', and all three users exist, 'uadmin', created during installation, 'rsk' and 'tk', created later, but only 'tk' is visible. It all looks ok from looking a the files (unique UIDs, UIDs > 1000 etc). Group memberships also look right.

i just ran a debug session with seb128 on IRC, http://paste.ubuntu.com/880205 is the output from running:
sudo /usr/lib/accountsservice/accounts-daemon --replace --debug

and then reproducing the user creation in gui

[Oliver Grawert (ogra)]

setting to confirmed and high .... confirmed on an ac100 armhf install here

[Sebastien Bacher (seb128)]

I can't confirm on i386, the users are correctly added and correctly reflected in the different ui bits (user panel, indicator menu, lightdm), it seems somewhat armel specific but I've no access to armel hardware to debug and that's not the sort of issues which can be debugged on a porter box environment, it needs a fully working desktop with sudo rights

[Sebastien Bacher (seb128)]

ogra said lightdm and the user panel gets confused, they both get their users from the accountsservice over dbus so let's assume the bug is in this component

[RoyK (roysk)]

Would it help somehow if I could expose a pandaboard on the net from here for debugging?

[Sebastien Bacher (seb128)]

Thanks for the offer, I will say "no" for now but maybe others are interested, it would be way easier to debug for somebody having some local access to a box with the bug than trying to debug desktop issues over ssh and I've already enough on my TODO, I might come back later to it if I run out of things to work on and nobody picked it up though

[Jack Wasey (jackwasey)]

confirmed on precise powerpc

[Jack Wasey (jackwasey)]

For powerpc, this is fixed in debian with package 0.6.15-4. The problem was something to do with assuming a "long" was 64 bits.

[Ivan Zakharyaschev (imz)]

I had this problem with (1) the list if users on the login screen, and (2) the list of users in the "user accounts" subsection of the system settings after installing Ubuntu 12.04 on a Toshiba AC100 several days ago, as described at https://wiki.ubuntu.com/ARM/TEGRA/AC100 .

Then, thanks to Jack Wasey's comment, I tried to solve the problem by installing the package from Debian --
http://packages.debian.org/wheezy/accountsservice (see also the changelog: http://packages.debian.org/changelogs/pool/main/a/accountsservice/accountsservice_0.6.15-4/changelog ).

First, I checked that the currently installed package doesn't include the discussed fix. (Read "man dpkg" on how to get the information about the installed packages, and on how to install packages from files.) Then, tried to installed the Debian package by simply clicking on the download link in the browser -- the graphical package manager reported that it requires another version of libaccountsservice0. So, I downloaded both package files, and ran dpkg to install them.

After that, the login screen correctly lists all the users. Good! That's essentially all I wanted. Unfortunately, the "user accounts" subsection of system settings crashes. (But I can use the usual commands to change the password, add or delete users, etc.)

Now I think that the installation via "dpkg" might have left some broken dependencies unnoticed, so I'd better use "apt" to install the Debian versions of the package from the downloaded files; then I'd be sure that the dependencies were checked.

i've got this on PowerPC (g5 MacPro) and it's a big problem for me.

i can add to the description that in the xubuntu login screen there are a number of users listed corresponding to the number of users created BUT they all have the same real name (not username) as the last user created.

 i was sloppy though. i just turned on all precise-proposed.

THANKS !!

Yes, thanks! After the installation of accountsservice_0.6.15-2ubuntu9.2_armhf.deb from precise-proposed/main the accounts settings menu and the lists of users function correctly on my Toshiba AC100 (ARM) with Ubuntu 12.04.
