[SOLVED] Update source index?

arcus · 02-08-2019, 02:41 AM

Hello first time posting here;

Linux Ubuntu 16
Update managers not working

Code:

sudo apt-get update

Terminal Response:

Code:

E: Type 'gpg' is not known on line 1 in source list /etc/apt/sources.list.d/signal-xenial.list
E: The list of sources could not be read.

I think there is a wrong source file in the index, how do i fix this?
Thanks

so what is in that file on line 1?

arcus · 02-08-2019, 05:11 AM

gpg (GnuPG) 2.2.4

If it is a problem with the application Signal; I can remove it, since i do not use it anymore. I do get the same error message if i try and --purge remove it though.

pan64 · 02-08-2019, 06:19 AM

I think that line is syntactically incorrect, try to insert a # at the beginning.

Can you please paste the output from the following command so that we can have a look at your software sources.

Code:

inxi -r

If you don't have inxi installed and are unable to do so, please paste the output from:

Code:

for i in /etc/apt/sources.list{,.d/*}; do echo file: $i; cat $i; echo ====; done

Thanks. You need to delete /etc/apt/sources.list.d/signal-xenial.list - it's not constructed properly.

However, the rest are also a hotch-potch. You should not mix repositories from different Ubuntu versions. You have a mix of bionic, trusty, precise, xenial and, for good measure, Debian Jessie. I'm honestly surprised that your system is still working.

Let's go back to basics. Exactly which version of Ubuntu are you running (inxi -S). You say 16, but your software sources disagree.

arcus · 02-08-2019, 05:55 PM

System: Host: Progress-2 Kernel: 4.15.0-42-generic x86_64 bits: 64 Desktop: Gnome 3.28.3
Distro: Ubuntu 18.04.1 LTS

thanks that worked, i'll just delete some of those other programs now.

We first have to sort out the repositories. Deleting or purging a program does not delete the associated repository.

Looking through your sources, which of the following do you still use?

Brightness Controller, Google Earth Pro, Tor Browser (or PDF Redact Tools), Runescape, Seafile Drive Client, Signal, Steam.

arcus · 02-08-2019, 06:11 PM

brightness controller, google earth pro, steam

arcus · 02-08-2019, 06:15 PM

and runescape

hydrurga · 02-08-2019, 06:31 PM

Thanks. You can delete:

/etc/apt/sources.list.d/micahflee-ubuntu-ppa-bionic.list
/etc/apt/sources.list.d/seafile.list
/etc/apt/sources.list.d/signal-xenial.list

(It seems that Runescape (https://www.runescape.com/download) is advising that you grab the trusty version no matter which Ubuntu-variant you have, unless they haven't updated their website. Similarly, Steam only appears to have a repo tagged 'precise', so we'll leave these alone. It's a pity though that these guys aren't either creating repos for each Ubuntu version or completely getting get rid of any version tag rather than causing potential confusion and mixing of version repositories. Such is life.)

Once you've deleted the above files, run:

Code:

sudo apt update

and

Code:

sudo apt upgrade

arcus · 02-08-2019, 08:16 PM

Thanks, I did exactly this.

hydrurga · 02-08-2019, 09:15 PM

Ok. Let us know if you have any other issues.
