Could not download all repository indexes

[jamesofyorkshire]

Hi.

When I try updating my PC, a box pops up with this in it:

An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repo.skype.com/deb stable InRelease: The following signatures were invalid: KEYEXPIRED 1624268195 KEYEXPIRED 1624268195 KEYEXPIRED 1624268195Failed to fetch https://repo.skype.com/deb/dists/stable/InRelease The following signatures were invalid: KEYEXPIRED 1624268195 KEYEXPIRED 1624268195 KEYEXPIRED 1624268195Some index files failed to download. They have been ignored, or old ones used instead.

I haven't had any updates for a couple of weeks now. Is that because of the error message?

I've uninstalled Skype but the error message still pops up when I try to update.

Any advice on how to stop the message popping up and enabling me to update the PC will be much appreciated.

Thanks in advance.

You can disable/remove that PPA/repo in Software Sources.

I had the same problem with Skype, so uninstalled it, removed the source file, and removed the key. I'll just leave it until they update the signature. Provided you've already uninstalled Skype and removed '/etc/apt/sources.list.d/skype-stable.list' (you may have already done this with a CLI or GUI tool), here's how to remove the key:

Code: Select all

# List known keys and some information for them.
apt-key list

# Identify the relevant key ID, then remove it with:
sudo apt-key del KEY_ID

Be sure you get the right ID otherwise you will make a mess! It should be easy enough to find, as it'll say 'Skype' somewhere for that entry. And obviously replace KEY_ID with the actual key ID. I'm not sure if the above-poster's suggestion covers key management, as I always do these things in terminals, so this is all I can offer you, I'm afraid.

This command may remove the key for you, assuming it's as you showed above:

Code: Select all

sudo apt-key del '1624268195'

I even installed and removed Skype all over again, just to be sure I had it all correct.

I haven't had any updates for a couple of weeks now. Is that because of the error message?

Yes, I expect so.

[sleeper12]

This might update the key:

Code: Select all

 curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add -

...

You beaut'! That worked a treat. I figured it would lead you with two keys for Skype, but nope! Sorted. If only I'd known that before I made a video about it on YouTube.

[sleeper12]

Well, good to know that actually works. I think I found it somewhere on an Ubuntu site.

[Termy]

I just dug through my notes to actually take note of this, and found a really old entry from back when it was in beta, with that exact command! You'd think they'd have sorted it by now.

[sleeper12]

I assumed it was something new. At least it still works.

[isahk01]

Just tried but not working.

[Termy]

That's unfortunate. I wonder why it worked for me and not for you. I did completely uninstall it first, install it, then added the key via the above command; did you try that?

[jamesofyorkshire]

Having followed the video made by Termy and totally uninstalled Skype, how do I re-install it? I've tried Synaptic Package Manager but it's not there.

Having followed the video made by Termy and totally uninstalled Skype, how do I re-install it? I've tried Synaptic Package Manager but it's not there.

Open up a terminal, then paste in the following one-liner:

Code: Select all

(cd /tmp && wget -q --show-progress 'https://go.skype.com/skypeforlinux-64.deb' && sudo dpkg -i skypeforlinux-64.deb)

Then press Enter/Return. It will go to your '/tmp' directory, download the Debian package for Skype straight from M$, then have your package manager install it. Skype will only be installed if there aren't any issues with the download and the '/tmp' directory exists. It should go smoothly. If you have any issues, let me/us know.

[jamesofyorkshire]

When I put that line into the terminal it downloads then says:

'dpkg frontend is locked by another process'

[jamesofyorkshire]

I rebooted the PC and tried again. This is what came up in the terminal in response to that one line you quoted previously:

(cd /tmp && wget -q --show-progress 'https://go.skype.com/skypeforlinux-64.deb' && sudo dpkg -i skypeforlinux-64.deb)

[Termy]

You could try addressing unmet dependencies with: sudo apt-get install -f If it works, Skype should finish installing.

Code: Select all

dpkg frontend is locked by another process

That above error message should just mean the package manager is busy, so you should have waited for a bit, for it to finish.

[jamesofyorkshire]

I waited 2 hours+. I didn't close the terminal.

I've done:

sudo apt-get install -f

...and it's removed Skype!

I'll try going through the process again.

[Termy]

Usually that command will remove packages whose dependencies could not be met. It's a shame M$ don't offer an AppImage. What's your version of Mint? Actually, please post the output of inxi -Fxxxrz within code ([code]like this[/code]) tags. Maybe you're using a really old version of Mint (and so Ubuntu), or maybe you're using something like PPAs which are providing old libraries Skype needs, overriding those in the official repositories. Have you compiled anything yourself?

[jamesofyorkshire]

'Have you compiled anything yourself?' I'm not clever enough to do anything like that!

As I suspected, you're using a version of Mint based on Ubuntu 16.04, which has reached the end of its long-term support of 5 years. You should upgrade your installation of Mint to the 19.* or 20.* range. Linux Mint 18 (Cinnamon) first released in June 2016, over 5 years ago.

Using an out-of-date installation of an operating system puts you at risk and will continue to give you headaches like this Skype installation — while Linux is great for security, it's no exception.

Here is a list of versions of Linux Mint.

Due to Mint 18 being EOL and you using a 4.4 kernel, I assume you also have other updating issues far greater than with Skype.

[jamesofyorkshire]

OK. Thanks a lot for your help. I was thinking of installing a newer version of Mint. I will do so now.
