A small Ubuntu 13.04 virtual machine instance I run in a cloud environment regularly becomes slow/unresponsive because of a proces called check-new-release. Is there any way to disable this process and maybe run it manually instead?
apt-get remove ubuntu-release-upgrader-core
The script that you're seeing running is
/usr/lib/ubuntu-release-upgrader/check-new-release, and removing the above package will remove that script completely.
A description of this package is:
ubuntu-release-upgrader-core - manage release upgrades
1note: uninstalling this package can prompt the removal of several other necessary packages. You can also disable the script (by emptying / commenting out the contents), or, it might only be called by motd, in which case removing / commenting out 91-release-upgrade in /etc/update-motd.d could work.

FYI: On an old 14.04 machine: apt-get remove ubuntu-release-upgrader-core python3-update-manager REMOVED: ubuntu-release-upgrader-core update-manager-core python3-distupgrade python3-update-manager– sarlaciiMar 15, 2022 at 7:50

You can also do this through the GUI, but that may not be appropriate for a virtual server.
You can do a manual check for a new release with

1hmm, I gave the answer a point up, but had to take it back. I'll wait and see and then come back. I'm in the same boat, no GUI because it's a virtual server on digital ocean.– ThufirFeb 8, 2014 at 7:09
Me too, all my servers just had their cpu pegged for ~60 seconds by this process at the same time. Not cool! Also on digitalocean– KevinMar 18, 2014 at 23:03

It is a pain on low RAM servers and 'Prompt=never' did not work for me on Ubuntu 18.04 so what I did (exit code 1 means NO_RELEASE_AVAILABLE):
mv /usr/bin/do-release-upgrade /usr/bin/do-release-upgrade.bak; echo -n 'import sys; sys.exit(1);' > /usr/bin/do-release-upgrade chmod 755 /usr/bin/do-release-upgrade # chattr +i /usr/bin/do-release-upgrade
