[SOLVED] syslinux, syslinux-common: unmet dependencies

[GekkoP]

It's been a couple of days now I've not been able to d-u.

This is the result of 'apt-get dist-upgrade':

Code: Select all

The following packages have unmet dependencies:
 extlinux : Breaks: syslinux (< 4:4.05+dfsg-6+deb8u1.3) but 4:4.05+dfsg-6+deb8u1.2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

This is what happens when I follow the suggestion and use 'apt-get -f install':

Code: Select all

Suggestions? Do I simply have to wait for the right packages to come in the repos?

I had that a few days ago. I waited, but heard nothing and could find nothing, so felt it only lied with me.

My solution

Code: Select all

purge syslinux syslinux-common extlinux

From what I could gather, they were not need, e.g. we use grub over syslinux. From there all was well. It quite possibly could be those packages are needed for [x] situation, but I have not been effected at all.

^ That fixed it for me too, thank you.

Right, you don't need these packages - they came from experimental, so your other solution would be do force the version from unstable:

sudo apt-get install packagename=version
