Script is having an issue with wget evidently on Ubuntu Wily, though I can't imagine why since this script has been running fine for years and I use wget frequently and haven't noticed any changes:

Do you have any insights? If I manually download the Ubuntu Mainline .deb's I can still say "no" when it asks if I want to delete and it installs fine, likewise with the dpkg line above..

I just used it to install a kernel on Xenial, it worked no problem

i used the -nc option in wget

  -nc, --no-clobber              skip downloads that would download to
                                 existing files (overwriting them).

this is to prevent wasting time downloading a file that is already present
can you verify the -nc option works in wily
i just deleted my wily install files last weekend (replaced with xenial )

Do you have some kind of custom default settings for wget? maybe an alias to replace it and use another options (cause you are too lazy to type the option every time)

This is some of what you're looking for I think:

And now that you mention, I forgot that I did set a wget alias:

seann@black-beast:~ $ alias
alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'
alias egrep='egrep --color=auto'
alias fgrep='fgrep --color=auto'
alias grep='grep --color=auto'
alias l='ls -CF'
alias la='ls -A'
alias ll='ls -alF'
alias ls='ls --color=auto'
alias wbfs='wit copy --wbfs'
alias wbid='wit ID6'
alias wget='wget -c --tries=0 --retry-connrefused'
alias youtube-dl='youtube-dl -f best'
seann@black-beast:~ $

The man page didn't say there were any conflicts with -nc though. Unless it's because -nc alters the default behaviour of wget. The aliased option I've added are only applicable for partial files though and shouldn't interfere when starting fresh. Should they?

I'll try ditching the alias and see what happens.

@GM-Script-Writer-62850

You could just remove the -nc option from the script or make a new alias and have the script use that
https://github.com/GM-Script-Writer-62850/Ubuntu-Mainline-Kernel-Updater/blob/master/KernelUpdateScriptGenerator#L198-L201
i wonder if the order of the options matters...

The problem was my alias. And no, order doesn't matter because wget checks all the options given before it does anything with them. I'll leave -nc in the script though and rename the wget alias since I don't always need those options active every time I use wget.

alias reget='wget -c --tries=0 --retry-connrefused'

OK, I was wrong. I changed my wget alias and tried again with the new 4.5.3-wily kernel, and I still got the same error. I was out of town for a while, so I'm only getting back to this now.

So I changed wget -nc to wget in /tmp/kernel-update and it worked fine. I found that odd, because you said you tested on Xenial and the script worked as-is, so I tested a live environment for Xenial from a USB drive, and I noticed there are several changes to the commands between Wily and Xenial. apt-get no longer supports --force-yes on Xenial for example. There are a few other minor things as well, but I suspect this is the root of the problem. Things that worked on Wily don't work the same way on Xenial due to changes that were made to some of the core apps.

Output with -nc removed on Wily:

The unmodified script runs just fine in the Xenial live environment with wget -nc but fails on Wily. When I version-check on Wily, I get:

GNU Wget 1.16.1 built on linux-gnu.

When I version check on Xenial, I get:

GNU Wget 1.17.1 built on linux-gnu.

Hope this helps!
