Update problem [solved]

[mikep]

Hello Folks,

I'm having a problem with system updates. I keep being told not all updates can be installed, and to run a partial upgrade.

Problem is, when I try that, the upgrade threatens to uninstall Virtualbox 6, which I rely on. Therefore I keep cancelling the upgrade.

Any help much appreciated.

Mike

Xubuntu 18.04
Virtualbox 6.0

What's the output from:

Code: [Select]

sudo apt-get update

and

Code: [Select]

cat /etc/apt/sources.list; for X in /etc/apt/sources.list.d/*; do echo; echo; echo "** $X:"; echo; cat $X; done

I freely admit to being a bit baffled...

[Mark Greaves (PCNetSpec)]

Can you run:

Code: [Select]

mousepad /etc/apt/sources.list

and post the contents of the file that opens back here.
(I'm pretty sure the contents are listed above, but just wanna make 100% sure of the formatting)

Okay, first let's backup that file before editing it .. run:

sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.backup

now open the file for editing

Code: [Select]

sudo mousepad /etc/apt/sources.list

and make it read

(MAKE SURE YOU GET ALL OF THAT, IT SCROLLS)

SAVE the file and exit mousepad.

Back in the terminal run:

Code: [Select]

sudo apt-get update

if you get NO errors, try running

Code: [Select]

sudo apt-get upgrade

and (before accepting any changes) see if it still says it wants to uninstall virtualbox ?

[mikep]

I did get errors Mark - see below.

To add to the fun, my internet connection keeps dropping out then coming back. I assume either BT or my ISP is working on it as I type, since the router seems to be quite happy and claims to be connected. I re-booted it to be on the safe side. Maybe the drop-outs explain some of the problems below (I'm thinking of the last five lines in particular)?

Thanks for your help, as always. Forgive me if I don't respond tonight. I may not be able to..

[Mark Greaves (PCNetSpec)]

Can you try

Code: [Select]

sudo apt-get update

again and see if you still get errors ? .. because I think those errors may have been due to an internet dropout

[mikep]

Thanks Mark,

My connection seems fine tonight, and the software updater has popped up saying that updated software is available. No mention of partial upgrades.

Virtualbox is listed under "install or remove" and the technical description says
Installed version: 6.0.8-130520~Ubuntu~xenial
Available version: 6.0.14-133895~Ubuntu~bionic.

Which course of action would you think is safer? Running the software updater, or not?

[Mark Greaves (PCNetSpec)]

Let it upgrade Virtualbox:-

a) it's a newer version (6.0.14)
and
b) it's the right version for your updated system (ie. bionic rather than xenial)

[mikep]

Will do Mark,

Sorry for the lack of response. Bit busy this end.

I'll report back once I've done it.

M

[mikep]

Ok, I'm now running the new version and it seems to be fine.

It's a bit odd though. I deliberately unticked Virtualbox from the list of updates, as I had problems once before with upgrading it and wanted to postpone any possible problems until I have a bit more time on my hands. However, software updater blithely ignored my choice and upgraded anyway. Luckily it seems to have worked, but it's a bit cavalier in my view. Almost like having a referendum and then blatently ignoring the result... 

Thanks again Mark. I'll call this solved now.

You're not kidding...
