First, boot to recovery mode or boot from the CD again. That gives you root access and you can change passwords using passwd. Also, you can view /etc/group and /etc/passwd to see if your regular signon was modified. Note: no one else here has yet reported a problem with the *command-line* utilities, so check that the symptoms match, etc. -crt On 9/12/07, teach2471 [EMAIL PROTECTED] wrote: terminal window, I used the command line added some users via adduser.

Re: [Bug 26338] Re: Adding a user to a group modifies other users' groups and passwords
Likewise, most of the reports did very simple things. I tried to add a new user. (However, it's also likely that a defunct user of the same name was in /etc/group or /etc/passwd because once upon a time those had been copied from another machine.) But it stands to reason that it doesn't happen all the time, or developers would have noticed that they lost sudo. Anyone have a fresh spare machine they can experiment on? Does this happen from a fresh install? If there's extraneous entries in the files? If you mix adduser and users-admin? Or useradd? I'd rather not muck around with my work system, as I'm not convinced I've localized the damage. My office might be able to dig an old machine out of storage, but I'm swamped for the next week at least. -Charles Twardy On Mon, 16 Jul 2007, David Green wrote: DGHmm Well it has been a while since I looked at it but all I did to DGcreate the bug was use the GUI user-admin too to reassign a user to a DGgroup.

[Bug 26338] Re: Adding a user to a group modifies other users' groups and passwords
=== Summary === I've just reviewed the duplicates, and marked a few others as duplicates. The problem seems to be that the graphical users-admin tool has some SEVERE bugs that make a system unusable and insecure. It makes several unintended changes to /etc/group under various conditions, including: * stripping group membership from all/many accounts when adding a new user * allowing non-admin accounts to change the root password * deleting accounts other than the selected one (?) Bug #64698 has a good statement of one manifestation. Symptoms include: * User no longer in sudoers (because no longer in admin) * Network failures (because haldaemon is no longer in appropriate groups) * Sound failures (because user and haldaemon are no longer in audio) * USB and other devices no longer working (haldaemon again) * Gnome login problems (audio? hal? networking?) Very likely this bug is causing a whole host of mysterious bugs that never got tracked back to /etc/group, because the symptoms are apparently unrelated. One method to recover: * Reboot to recovery mode (a.k.a. single-user) * Edit /etc/group: * add the appropriate accounts to admin and audio (etc) again * add haldaemon to: cdrom, floppy, audio, plugdev, powerdev (maybe others, but that's what I found) I am attaching my reconstructed /etc/group, to help people recover. I _appear_ to have everything working again (sound, network, gnome login, sudo) though I may yet have missed something, or your system may have other bits. It's been slightly anonymized -- users daffy, bugs, marvin and donald are fictitious. Hope this helps. Other possibilities including reinstalling hal and/or udev to reset those permissions. (sudo aptitude reinstall hal hal-device-manger). Mind you, I'm deleting users-admin from my system for now. ** Attachment added: Fixed-up /etc/group file http://launchpadlibrarian.net/8449978/group ** Attachment removed: Fixed-up /etc/group file http://launchpadlibrarian.net/8449978/group -- Adding a user to a group modifies other users' groups and passwords https://bugs.launchpad.net/bugs/26338 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 26338] Re: Adding a user to a group modifies other users' groups and passwords
Still a problem -- I just hosed my system trying to add a user. It basically lost everyone's group membership. That knocked me out of admin, and killed network functionality (especially gaim) because lots of userids should be members of haldaemon, but no longer were. Not knowing who had lost what, I poked around until, by removing and reinstalling dbus and hal (etc.), I got network back. I still don't have audio, because I haven't figured out which groups need what, or what reinstall will fix my /etc/group. I had to reboot to single-user (recovery) mode to add myself back to admin so I could sudo. What a dreadful bug. Completely unexpected that a simple add user operation would hose the system. -- Adding a user to a group modifies other users' groups and passwords https://bugs.launchpad.net/bugs/26338 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 86749] Re: evince does not automatically set or remember the paper size
I'm not sure this is an instance of bug #349102. I don't think this is about remembering configurations. It is about ignoring system configurations. I have the same problem in reverse. For example, my copy of evince insists on printing an a4 document as a4, despite my system papersize being letter. Acroread correctly notices my system settings, and is able to print. Evince is basically unable to print, because my printers demand A4 and won't be deterred. Evince does not allow resizing either. -- evince does not automatically set or remember the paper size https://launchpad.net/bugs/86749 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
