Unmet Dependancies
 

HI All,

I am running Elementary Linux(elementary OS 0.4.1 Loki,Built on "Ubuntu 16.04.2 LTS" Linux 4.4.0-66-generic)

When I try to install software from the app store or via command line I get errors a typical message is shown below.
Any assistance would be very welcome.

ou might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

did you read this? it is written in plain english, therefore it is meant to be read by humans (and acted upon). also please use code tags next time you post code to the forums.

No clue on what they are doing most likely going to end up with dead system if that is any indication of the packing skills if you ever get to install anything, that said try this.

This will show you what is available to install use similar to this for the name of the package you need/want to install.

As you can see quite the fun time getting stuff like that installed, you would need to remove the -s from the install line for it to install.

...run 'apt-get -f install' to correct these...

copy and pasted from your origianl post. Plus mentioned in previous posts.

$ sudo apt-get update
$ sudo apt-get -d dist-upgrade
$ sudo apt-get dist-upgrade

My usual update path. The -d for download only so I can do the first two a couple of times if I have a lot to get and there's new updates before the previous updates finish downloading.

I did read that thanks and acted upon it. I did however forget to show the results.

I see 'disk full' errors. Can't be good for pkg mgmt!!!

Hi KelsoJIm and welcome to LQ.

!!! has it correct, and unfortunately this indicator was not present in your first post. Meanwhile, post # 5 includes these things.

The first one indicating how much space you should expect to need to install these packages:Next it goes to fetch the packages, however fails, as indicated by !!!:It is usually helpful to review what the output says. I realize it seems like a great deal of information, however some key things are:

1. If you are prompted, it usually is for a reason, therefore when it tells you about disk space and asks you if you wish to proceed, it is helpful to just be aware of what it is saying, which may or may not be relevant. Such as if you have hundreds of Gigabytes of free disk space, using up less than 1 Gig of space is no big deal. However this does not seem to be the case here.
2. Many of the tedious reports, sometimes you see at the start of a line any of, E: W: (E) or (W) perhaps also C: and (C) where the capital E means ERROR, the capital W means Warning and maybe not so bad, and the capital C means Critical. But scanning through the detailed output, if you see these pre-pended at the start of lines, they could indicate where the problem occurred.
3. Finally, the last few statements when something has failed are helpful. Many times things fail, and in fact the failure may be far back in the output, however it continues to fail, because it tried one thing, failed, so moved onto the next thing and continued to fail. Therefore the remainder of the log may also indicate the problem.
4. Once again, I know these outputs can be tedious or overwhelming, sometimes I copy and paste all of it from the terminal and into an editor and then just search for error, warning or fail, that also helps.

After all that ... how bad is your disk space? Do you knowingly have a lot of stuff on it? Or do you need advice about how to learn where the space is used and what you can consider to do about it?

No space left on device

You definitely need to deal with that. Various routes for quick space by removing -doc packages or removing downloaded .deb files from /var/cache/apt/archives/. Otherwise you need to allocate more space or otherwise move /xyz/ things to other space.

Hi All,
Firstly thanks for taking the time to assist. Much appreciated.

I have read a bit and ran the following:

dpkg -l | tail -n +6 | grep -E 'linux-image-[0-9]+' | grep -Fv $(uname -r)

to show up my old linux images in order to remove them to free up space.

I got this list of Linux images and would like to delete the old ones to free up space.
Any suggestions to safely remove these would be appreciated.
Thanks

Can you paste the output of 'df -h' ?

Here is a relatively safe command to free up space by deleting old packages that your system doesn't think it needs any more:

I can see from the output in post #5 that this should delete some of the old 'linux-image' packages.

autoremove gives this.

Is this the problem here?
