David R.'s questions

I would like to be able to search all my images metadata when searching via Nautilus or Activities. So far I have not been able to do anything more than search image file names.

I know that GNOME uses tracker to index files and run the integrated search. But when I search for a tag I've added to an image file, that file is not returned as a result. Either when searching via Nautilus, Activities, or on the command line.

I tried tracker search -i Road and received no results.

If I run tracker info imagename.jpg, a little ways down the returned list is:

'nao:hasTag' = 'urn:tag:Road'

I also tried using dconf-editor to browse the settings, as suggested in the documentation for tracker. I did not see any settings that jumped out as helpful. Maybe I just missed something?

System info:

$ cat /etc/lsb-release

DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

$ tracker --version

Specifically, I have to set which of my two monitors is on the right every time I reboot. I'm using gnome-control-center, in Gnome3. Ubuntu 14.04.

Why are my settings being reverted when I reboot?

There's obviously a way to check to see when an update is a security update. I often get greeted by a motd that says "there are N security updates."

What I'd like to do is have my server email me a list of what packages need updating for security reasons.

To take it a step further, the email would link to the applicable security notification from Ubuntu.

Basically, each server is somewhat unique. I've received several emails on the security mailing list for packages I do not have install on any/all servers. So I'd like each individual server to tell me what it needs. That way I can apply updates in a timely manner, while avoiding restarting services like Apache that would cause users to have some downtime.

How could I do this?

I am using LDAP authentication on my Ubuntu 11.10 server. I installed libpam-ldap, and configured things accordingly. It works great, except that I get this error every once in a while when I try to sudo:

sudo: setreuid(ROOT_UID, user_uid): Operation not permitted

I know I have sudoers set up correctly, since it works most of the time. It's not just my log in either, others have the same problem when I have it. When this error is occurring, I can't ssh in with my regular system user at all. When I sign in directly, I can't get any gnome-terminal to start.

Once I restart the server, the problem goes away. 'Course, that's not a solution, if it was a prod server, I'd be in trouble.

How do I fix this?

Edit 3/1/12: I just figured out that if stop and start the nscd service, the problem goes away.

service nscd stop
service nscd start

Not much of a solution since I have to be logged into the server directly, not via ssh.

As the subject says, I'm trying to add a new user. When I run the command, it says the user already exists. But looking in /etc/passwd, /etc/group, and /etc/shadow shows that the user does not exist.

Running the command on my local machine works just fine. I'm running Ubuntu 11.10 on both.

Here's my terminal commands and output:

root@ws-prod-www-01:~# useradd -s /sbin/nologin -m -d /var/www/html/atc -g 33 -u 10141 atc
useradd: user 'atc' already exists
root@ws-prod-www-01:~# grep atc /etc/passwd
speech-dispatcher:x:111:29:Speech Dispatcher,,,:/var/run/speech-dispatcher:/bin/sh
root@ws-prod-www-01:~# grep atc /etc/shadow
speech-dispatcher:!:15259:0:99999:7:::
root@ws-prod-www-01:~# grep atc /etc/group
root@ws-prod-www-01:~# 

I also tried:

root@ws-prod-www-01:~# adduser --shell /sbin/nologin --home /var/www/html/atc --gid 33 --uid 10141 atc
Warning: The home dir /var/www/html/atc you specified already exists.
adduser: The user `atc' already exists.
root@ws-prod-www-01:~# 

Any thoughts?
