To see these PPAs when you run sudo apt-get update, look at the lines that say W: Failed to fetch: 'url of ppa' Now go to Software & Updates > Other Software and remove the conflicting PPAs.

Look at what has changed in the log file: sudo tail /var/log/auth.log - it is just a text file, after, all.

You can do sudo apt-get -y upgrade this will assume yes to most things. In some cases where yes may be undesirable the command will abort. A more risky option is sudo apt-get --force-yes this is not recommended as it could say yes to something that will break your system. For more details on these options you can run the command man apt-get

You can do this by adding a say upgrade alias to ~/.bashrc, and by running the alias to perform the upgrade: Mark your script as executable: chmod +x <path_to_script> *<path_to_script> = path to the script you want to run Add an upgrade alias to ~/.bashrc: <<< "alias upgrade='sudo apt-get upgrade && <path_to_script>'" ...

Tracing back to conflict between minidlna and sophos Anti virus (still don't know why they go in a loop while apt update), Uninstalled sophos using sudo sh /opt/sophos-av/uninstall.sh Now I am able to proceed. Hope it helps some one else facing this issue.

One issue is that the sav-* scripts mentioned in your output seem to be missing a LSB-header. If that is some Sophos Antivirus stuff, better ask Sophos about it. If all else fails, try to add the LSB tags manually to /etc/init.d/sav-web and the other two.

Not installing security updates creates a situation in which hackers can use your machine to tamper with your data and use your machine to attack others. For example, an operating system that is using OpenSSL that has not been updated can be tampered with and cause your data to be leaked.

If you know of a specific fix or improvement in how the newer kernel handles your hardware, I say go for it.

After trying every configuration I could find for the emulator as well as ...

Given you are seeing "fork failed: Cannot allocate memory" I'm guessing you have run out of memory or a related resource. Try closing you browser and other memory hungry applications before you reattempt. A reboot would also help.

The README seems to be outdated (you don't want raring backports). Just add a line for a CRAN mirror, e.g. the CRAN master in Vienna: deb http://cran.at.r-project.org/bin/linux/ubuntu trusty/ Alternatively you could use the Ubuntu R PPA, which can be added using the following syntax: sudo add-apt-repository ppa:marutter/rrutter

Support for Ubuntu 13.04 "Raring Ringtail" ended 2014-01-27 so most mirrors don't provide raring-backports any more. As you are using Ubuntu 14.04 und already have trusty-backports activated there isn't any reason to use the package source anyway. Just remove it.

Remove this line: deb http://mirrors.ocf.berkeley.edu/ubuntu/ raring-backports main restricted universe and use this list to select a mirror. As Florian Diesch has already answered: Support for Ubuntu 13.04 "Raring Ringtail" ended 2014-01-27 so most mirrors don't provide raring-backports any more.

So I fixed this and I feel really dumb for not knowing this. Okay, the problem was that at some point, I added the 1386 architecture instead of i386. So when I tried to update with apt-get, it couldn't download the 32-bit packages. Thanks.

Sometimes happens. A possible solution is removing and readding your Ubuntu One account. To do that, please go to System settings -> Accounts, select your Ubuntu One account, click on Remove account and then readd it. After that, try again to download updates.

You can add & modify files in RW mode, and then do an OTA update, yes. However we never test this scenario, so if it doesn't work, or the files disappear, you'll probably need to cleanly re-flash the device to 'reset' back to a working state.
