When I try to update my Ubuntu 20.04 LTS from terminal I get this error message, any help please?

N: Ignoring file 'rethinkdb.list.save.1' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'rethinkdb.list.save.2' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Type '“deb' 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.

  • how about removing them from /etc/apt/sources.list.d/? – Rinzwind May 25 '21 at 09:06
  • Thank you! I am beginner and I don't know how to do that – F.Marko May 25 '21 at 09:07
  • @Rinzwind I have just checked it and there seem to be many options, I am afraid that I chose the wrong one. Could you tell me how to delete them please? – F.Marko May 25 '21 at 09:11
  • Mind that that is not the problem you want fixed ;-) It is the "type '“deb' is not known on line 1 in source list /etc/apt/sources.list.d/signal-xenial.lis" That one is fatal. The other one is ïgnored" so not really an issue. – Rinzwind May 25 '21 at 09:15
  • Oh, really? aren't there any solutions? – F.Marko May 25 '21 at 09:16

The "ignored" message will be fixed with: cd /etc/apt/sources.list.d/ && rm rethinkdb.list.save.*. Mind that a remove is permanent but also that "ignored" is not a fatal error: the system will continue.

E: Type '“deb' 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.

... is fatal though. Use an editor and check /etc/apt/sources.list.d/signal-xenial.list and fix the error. OR remove the file (as it refers to xenial = 16.04) with ...

cd /etc/apt/sources.list.d/ && rm signal-xenial.list
