I recently tried to upgrade to xubuntu 16.04. My computer froze in the process, and I had to reboot. When the computer came back on, it gave me just a black screen like the terminal. I tried to finish the upgrade from there by trying get install upgrade (I don't remember the exact wording). To all appearances, it was successful, but I'd like to be sure. I'm having problems with my internet (I know that's a common bug, but none of the fixes is working for me. I'd like to at least be able to eliminate upgrade incompleteness as a possible cause of those problems.

Addendum: My computer is notifying me that a couple of updates are still undone. It says it needs internet to do them . Right now, I can't connect. I'm. Not sure how basic they are to my system, and I don't know how to find out.

We'll need the EXACT cmd and err msgs, even if it means typing them in by hand.
Otherwise its going to be very tricky

Describe this upgrade process please?
from/to
inplace/bootable media...

details? Thanks.

I was still using Xubuntu 12.something. My computer prompted me to upgrade. I clicked the button and put in my password. I didn't do it from the command line.

After the computer stalled and I turned it off and back on, it went to a black screen like the terminal. I tried sudo apt-get upgrade, in the hope that it would finish itself. To my computer illiterate eyes, it looked like it picked up more or less where it had left off, but I would never really be able to tell.

It had a minor problem with Gimp. I don't remember what it was. Sorry, it's been a few days. At any rate, I found my error on the internet and applied a commonly suggested fix, which seemed to work. The upgrade seemed to finish normally, although it told me "some index files failed to download. They have been ignored, or old ones used instead."

I get that message every time I install something. Usually, the program still works fine. I've been meaning to try to figure out what to do about it, but I just haven't gotten around to it. I don't know if it's a problem in this case or not.

When I rebooted the computer, it went straight into what looks like Xubuntu 16.04. It really seems to have been successful. My word processor, PDF viewer, and CD/DVD player are all working normally. When I opened a document in my word processor, it did so with LibreOffice 5, which is a newer version than what I had before.

When I typed "cat /etc/issue" into my terminal, it gave me Ubuntu 16.04.01 LTS /n /l.

Only the internet isn't working normally, and I know that's an issue that several people have had with the upgrade. I'd just like to make sure, if there's a way to do that. Interrupting an OS upgrade is potentially serious, and I find it a little hard to believe that I managed to fix the whole thing so easily.

I have another question. When I first logged in to my computer after upgrading, it prompted me that there were two more updates that required an internet connection to install. It hasn't prompted me since then. Is there a command I can use to find out what they are?

When I go to the software updates in my menu, it just says "Failed to download repository information. Check your internet connection."

Have you tried connecting to your router, and thence the internet, with an ethernet cable?

I haven't. Let me go home and try that.

Hello and welcome to the forum

EDIT: Please try hydrurga's and Habitual's suggestion below and see if that works before posting the information I've requested below.

Also, if you would, if the ethernet connection works, please open a terminal and post the results of these commands...

If this is a laptop, please also include the results from...

I'm glad the rest of it works well, though.

In addition to ardvark's advice, I would also advise you, if the internet connection works over ethernet, to run sudo apt-get update and sudo apt-get upgrade. This could well solve your connection problem by, for example, downloading the relevant wifi driver. Worth trying first before hitting the diagnostics (in my humble opinion; if ardvark naysays this then no problem).

Hi...

I agree with your suggestion, that actually would be worth a shot.

to check what's "available" for upgrade, you can issue:
-s is "simulate" so you can get a nice idea of the upgrade.
should tell you what's going on and whether or not your system is considered a candidate.
If it is not,
then issue
and show us the output.
We may have to get dirty.
You have an bootable installation disk, if necesary?

Wow. Thanks for all of the responses. I connected to the internet using a cable. The first thing I tried to do (I hadn't logged on here yet) was to navigate to my software updater via the menu and install updates that way. It gave me this error message:

I did nothing and logged on here, instead. Per hydrurga's suggestion, I started with apt-get update and apt-get upgrade. When that finished, I restarted my computer. It absolutely solved my internet problem, which is an enormous relief.

Out of curiosity, though, I clicked again on my software updater through the menu. It gave me the same error message as before. Should I do a "partial upgrade"?

You're welcome

Awesome! I'm glad that worked.

Try this command first...

If that doesn't resolve the issue, try these commands, entering them one at a time...

Disclaimer: Be careful with these commands. Ones that are prefaced with "su" or "sudo" will essentially allow root access to your system. Mistakes could possibly damage or even destroy your OS.

Let us know how it turns out...

When I tried nothing happened. It asked for my password, then did nothing. It just gave me Then, I put in and At the end, it gave me

Hi audduck...

Does the solution here help? If not, take a look at the bottom solution (using Synaptic) here.

Just for future reference, when upgrading to a new version of a distribution, it is always advisable to do this by burning a new DVD of the (new) distribution and installing it from scratch.
