Found Expired SKS Keyserver Certificate for all EndeavourOS Installs

Hey everyone,

I was digging around my system a little bit and stumbled upon an expired SKS certificate which is located at /usr/share/gnupg/sks-keyservers.netCA.pem

I’m just wondering if anybody would know the severity of this? I’m not an expert at this stuff, but it doesn’t seem like it’s worrisome as an expired SSL cert or anything, but it still doesn’t seem like it should be something that is expired seeing that it handles encryption. This expired certificate has been here ever since the first time I used Endeavour almost 2 years ago, so it’s on every install and it’s bound to be on your guys system’s as well. I just wanted to bring it up and see if anybody has any information on the situation!

Thanks

Edit:

I also wanted to add that this doesn’t come up in other Linux installs such as Fedora, Debian or even vanilla Arch so it’s something to do specifically with EndeavourOS.

I have that file on my Arch system. It seems to be part of the package, gnupg coming from Arch.

Arch is getting from gnupg itself: https://github.com/gpg/gnupg/blob/master/dirmngr/sks-keyservers.netCA.pem

Looks like that certificated is expired as well.

The SKS keyservers do not even exist anymore if I remember right?

These where the default keyservers used for gpg on arch… changed to the Ubuntu keyservers now…

But wondering what it does there…
between all the helpfiles for gnupg…

I’m thinking this as well. The website https://sks-keyservers.net isn’t even up anymore. So does that mean that the certificates are on an EOS install but they’re not doing anything? Like I said, I really don’t know much about this stuff haha.

Would it be okay to just delete them or what?

EndeavourOS does not add these they came directly from gnupg sources, i checked also the arch package PKGBUILD and they do not add this there could be a leftover or for compatibility reasons. the path is generic shared stuff for gnupg… so it will be there for a reason.

Also saw that gnupg package is marked outdated for longer already… copuld be this will get removed with nthe next update already…

Better would be to find out why it is even there… place to ask ?

It’s not terrible to have an expired key laying around. If it was used to encrypt something long back, you’ll need the expired key to decrypt it.

I see no risk with leaving it as-is.

I have some old door keys around here somewhere… And as T6404 states, it’s not in use.

i trust Werner…
