I try to upgrade Ubuntu 14.04 to 16.04, but I have an issue.  I tried to follow this article :    after running this command :  sudo do-release-upgrade   When the 1022 ssh dialog appeared, I wrongly typed n, then I got disconnected.  Later on, I had to go to the Dashboard terminal, and restore the ssh connection.  But when I retried the command :  sudo do-release-upgrade   it gave me this message, and I had to close the terminal :  Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade has aborted. Your original sources.list was saved in /etc/apt/sources.list.distUpgrade.

I have a server running 12.04.4 32 bits Ubuntu server, and I wonder if there could be any unsolvable problem updating to 14.04.1 as the terminal suggest me (using do-release-upgrade) to do.

After executing this command  sudo apt-get update &amp;&amp; sudo apt-get -y upgrade   I get this error  W: The repository 'http://dl.google.com/linux/chrome/deb stable Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details.

The update from Ubuntu 13.10 to 14.04 LTS does not work it keeps showing me an error as could not calculate the upgrade, even when I want it to get updated from the terminal it says the same error. I did not use the beta its the final Ubuntu 14.04 LTS.I have restarted my laptop for like 5-10 times no change. Disabling the software sources also does not help.

I upgraded to Chrome 61.0.3163 via ppa on Ubuntu 16.04 but it won't launch because NSS out of date. Launching Chrome in terminal gives:  NSS &gt;= 3.26 is required. Please upgrade to the latest NSS, and if you still get this error, contact your distribution maintainer.

I havent used my Ubuntu for quite a long time.  Today, when I booted Ubuntu (14.04 LTS), the software updater and Software &amp; Updates (from Settings) are not working.  The software updater's window will show up for around 1 sec, but it will close automatically. Software &amp; Updates is never shown, no matter how many times I click the icon. Note that neither of them show any error message.  Those 2 features were working perfectly the last time I used Ubuntu. I want to do some system upgrade and update.  For now, I use sudo apt-get update &amp;&amp; sudo apt-get upgrade. This command runs very fast, meaning (I think) my Ubuntu is not updated properly. The update from software updater always has a big size hence the download should be slower.  What should I do?   Can I just uninstall and reinstall both of them? If I can, how to do it?  Just to clarify, I don't want to upgrade my Ubuntu version (I want the LTS one), I just want to upgrade the software/packages I used.  Thanks for your time.

When I upgrade from one version of Ubuntu to the next, the upgrade tool rightly disables all my PPAs, so that software compiled for or otherwise tied to the old version of Ubuntu does not interfere with the new version that I just upgraded to.  Is there any way to automatically re-enable and update any PPAs that provide packages for the new version of Ubuntu? For example, suppose I'm currently running Maverick, and I have two PPAs enabled, "foo" and "bar". Suppose that "foo" provides packages for both Maverick and Natty, while "bar" provides packages for Natty only. Is there a tool I could run after updating to Natty that would re-enable my "foo" PPA and update it to point to the Natty packages, while leaving the "bar" PPA disabled?

And what did I do wrong?  UPDATE I managed to get apt working again by downgrading to previous version (3.9.5-1ubuntu1). However, next upgrade led to the same problem.

We know that do-release-upgrade “does a release upgrade”. But at a little lower level what does it really do?  I plan to do a more manual upgrade, for instance the Debian way: aptitude update and aptitude full-upgrade after setting up the sources. Actually, I plan to do it entirely interactive with aptitude. But that leaves me curious about what else do-relase-upgrade does, except hosing up my sources.list.

I have seen and used all of these commands to upgrade packages on my system, but why are there different commands for this? Do they all not do the same thing? And if not, then in which situations would it be better to use a specific one of them?  These are the commands I mean:   sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt full-upgrade   I have already looked at this, but it does not answer my question about the command sudo apt full-upgrade:

I'm trying to upgrade from 18.10 to 19.10, using sudo do-release-upgrade however I only get an error: An upgrade from 'cosmic' to 'eoan' is not supported with this tool. I performed the steps to update my sources.list to point to old-release server, as suggested here:  This did not help. I get the same error.

I am using Ubuntu 16.04 Beta 2 at the moment and every time I try to update at home via sudo apt-get update or upgrade trough sudo apt-get upgrade I wont get any feedback. Even installing of anything will have the same result. It will just "hang up" on 0% while fetching data.  $ sudo apt-get update [sudo] password for niclas:  0% [Connecting to archive.ubuntu.com (2001:67c:1560:8001::11)] [Connecting to archive.canonical.com (2001:67c:1360:8c01::1b)]   I have no idea how to solve the problem. I already tried to ping6 archive.ubuntu.com with 100% packet loss while just ping wont have any loss.  I changed the DNS-Server (IPv4 &amp; IPv6) to Google's one no solution either.

I've been trying to upgrade my installation of Ubuntu 9.04 to 9.10, but all of the instructions I've found haven't been helping. They mostly say to run the update manager and it'll tell you that there's a new distribution ready. Well, mine doesn't say that.  Things I've run or checked:   update-manager -d says:     Your system is up-to-date   The package information was last updated less than one hour ago.  I've set it to get all new distributions, not just LTS  $ cat /etc/update-manager/release-upgrades [DEFAULT] # default prompting behavior, valid options: #  never  - never prompt for a new distribution version #  normal - prompt if a new version of the distribution is available #  lts    - prompt only if a LTS version of the distribution is available Prompt=normal  I'm definitely running 9.04  $ lsb_release -r Distributor ID: Ubuntu Description:    Ubuntu 9.04 Release:        9.04 Codename:       jaunty  Even running the release upgrade from console doesn't help:  $ sudo do-release-upgrade  Checking for a new ubuntu release No new release found    This is running from behind a proxy, but I've set it up such that the regular upgrades and apt-get etc doesn't complain. (export http_proxy=http://myuser:mypass@myserver:8080/)  Could you think of anything else which might be stopping me from upgrading?

So, is it possible to update and upgrade without running:  sudo aptitude update &amp;&amp; sudo aptitude upgrade   Meaning, is there one command that can do both?
