Ubuntu Installation :: Schedule Updates For A Certain Time Of Day?
Sep 1, 2011
My Internet service provider here in South Africa is Vodacom (Vodafone) and I pay a huge amount of cash for 2.5Gigs per month. They do, however, give me the same amount of data for free that I can make use of between midnight and 5.00am.For this reason, I would like to be able to schedule my update manager to download all updates at, say, 10 past midnight.Can any of you guys out there offer any suggestions or is there a way that we can make a request for the Ubuntu developers to include this in "Update Manager"?

I've been quite puzzled by the behavior of unattended updates - it seems it runs the updates at or before 7am (on all the server installs I've got). They are only set to do security updates unattended, but what I am wondering is if there is a way to change the time that they install? I want the updates to install early in the morning, at like 3am or such, so I can reboot the machine when I get up if needs a reboot.I found a few mentions about it, but nothing specifically talking about the time.[URL]..

I have just made a clean install of Ubuntu 9.10 and after installing all updates, GDM is taking a long time (about one minute) to come up after a clean boot, resulting in a regular console prompt.
If I issue "sudo service gdm start" it does come up promptly.
What can I do? Where can I see startup logs to try and identify any problems?

I have a select few users (finance dept.) at work who want to be able to write to a calendar based program on the network that allows them to schedule time / days off. The calendar or program needs to be writable by only a few administrators so that once time off is approved by their manager, he or she is the one who would access the application and submit the entry on it's specified date / time.
I would prefer if the back end is SQL database compatible but doesn't need to be since at this point I need to find anything that will fulfill this request. Obviously this sounds like a web / php based application that would run on my Apache Intranet web server

I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.

I've been having a problem on my AMD based machine, 4cpu, gigabyte ga-ma78gm-s2h Mobo, 8GB mem, two 2 terabyte Sata HDs.One thing I've found is that any kernel after 2.6.32-17 has a randomness at boot time whether the system will completely boot or not.
For instance just today I downloaded and installed 2.6.32-24
It fails to boot (I've tried cold boot, warm boot).Running its repair also fails to completely boot.My experience is that if I keep trying it "may" eventually boot but I believe there was some change after 2.6.32-17-generic that's causing the problem.Because as with 2.6.32.23... which also fails to complete bootup many times... eventually my guess is that 2.6.32.24 will also boot "sometimes".But why does 2.6.32.17 always boot for me? Something changed and its not my setup.

I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.

For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.

I got a message today telling me that there where 78 updates available. One of them was Kernel 2.6.29.6-213.fc11.i586 and when I installed all the updates and rebooted, my startup time was very slow. And when I checked the boot.log I noticed this:
Code:
Enabling the nvidia driver: *** glibc detected *** /usr/bin/python: free(): invalid pointer: 0x00f0e24a ***
[code]...

I have Ubuntu running as a Virtualbox, and every time it upgrades the kernel, the Guest Additions stop working.The install process in Linux requires using a virtual CD, running scripts from the command line, etc.Is there any way to keep the guest additions constantly working even when the kernel is upgraded? Can they be installed as Ubuntu packages instead of installing off the virtual CD?

I have the eight Debian dvds listed in my sources.list, along with security, nonfree, and multimedia repositories. It does this for all eight dvds, re-scanning them for the update.These dvds have already been scanned (from the apt-cdrom add command). New updates are NOT going to suddenly appear on these already scanned dvds, so this is a completely unnecessary endeavour.Is there a way to stop this?It didn't happen with Lenny, and I'd like to stop it with Squeeze.

every time when /usr/bin/puplet try to talk to yum-updatesd via D-Bus, yum-updatesd will crash. After restart of yum-updatesd and call /usr/bin/puplet from the console I get this message;

I want to have a terminal open and have something like a "repeating cat" command running in it for a certain text file (in particular /var/log/system.log). So my terminal will scan or cat the text file every so often or whenever the text file system.log gets written to by the system, it will display whatever it wrote to the file in my terminal that is open.

I just learned that warsow 0.6 is out, and went to see if it was available in the ubuntu software center yet, as opposed to going and downloading and installing it manually from the warsow website. The ubuntu repo's still have version 0.5, and at the bottom of the page it says:
"Updates: Canonical does not provide updates for Warsow. Some updates may be provided by the Ubuntu community."
So if I wanted to 'update' this item in the repo's for the better of the community what would that entail?

I'm very new to Linux and Ubuntu (about 2 days) and am having a hard time getting Ubuntu to work. I'm not completely sure that I'm posting in the right forum since I have several issues. I can't tell what's causing what.
I'm using the wubi installer for version 10.10 (i386 - 32 bit). I have an AMD 64-bit, but the wubi installer for that only crashes when I try to boot it the very first time. I get a blank screen and my tower is silent. Version 10.04 does the same. Version 10.10 is the only one that gets me somewhere.
So, I installed ndiswrapper and the proper driver for my USB adapter. Now I have 2 main problems:
1). the most relevant to this board is that when I use the update manager to get all 135 updates, I'm prompted to reboot to complete the installation. When I do that, i get the same blank screen and silent tower treatment. Oddly enough however, when I went back to windows, uninstalled ubuntu, then reinstalled it again using wubi, the update manager said that I already updated an hour ago (!?!?.. I assume it's still reading the old files from the previous install attempt). Unfortunately I messed it up anyway trying to fix my second problem...
2). my internet connection fails here and there. I don't know if it's ndiswrapper or the driver or what. Once it fails, it won't reconnect. I have to go into ndiswrapper, delete the current driver and reinstall it. This has happened to me while on the internet (scouring these forums) and while downloading the updates and whenever it feels like it.
Also, the system does freeze up on me here and there as well. Sometimes when I'm using ndiswrapper. Sometimes when I'm authenticating myself. Sometimes in update manager and sometimes in synaptic. Right now it's working. But I haven't updated yet and I'm afraid to try.

There are some updates in the Update Manager list which I do not install. Among them, some drivers for HP Printers (I don't know why this cropped up; I don't even use printers on my laptop), and gcj updates (I use gcc/g++ but not gcj). I unchecked them the first time I saw them on my UM list. However, for every subsequent batch of new updates, UM retains these updates and I need to uncheck them every time. How can I remove them totally from my UM list?

I want to schedule a Java program to run at a certain time, which will open a GUI progress monitor while it runs, and then terminate when it's done. I can execute it fine from the command line, but I it doesn't seem to work when I schedule it with crontab. In fact, I can't make any gui by scheduling it, not even something like gedit or firefox.
I know it's pretty rare that someone would want to do this, but is there any way to schedule a GUI app?

I have Postfix and Procmail installed on Hardy.
Are there any tips/tutorials for sending out scheduled email?
My main use case for this would be sending out a Tweet and an email at the same time.

I just did my first rsnapshot backup of my /home/ to an external harddisk. When I am not at my computer for a couple of hours, I always shut it down. Therefore, there are no predictable hours of the day where I know that my computer is running. So, how should I schedule/crontab my rotating rsnapshot backups?
Is anyone using rsnapshot in combination with a schedule which is not based on exact times but rather on the time the computer is running?

I'm running LXDE in Ubuntu 10.04, and NTP won't work properly for me. I've found that this command in a terminal will set my clock properly:
Code:
sudo ntpdate time.nrc.ca
But I have to do that manually.
How would I go about creating a shell script with that command and then scheduling it to run once a day?
