Hello.

I've installed Ubuntu 18.04 LTS and completed network settings. But network symbol at the top right corner looks like an '?'. I have internet access, but i don't have access to default repositories.

Can someone help?

What does it say/show?

It appears that the question mark is a known bug: https://askubuntu.com/questions/1029...d-of-wifi-icon

That shouldn't affect your software sources though, unless you really do have an intermittent wifi problem that's enough to put your package manager off its stride. It will be interesting to see what output you get from the command that ChuangTzu suggested above.

Thanks for quick respond. I've deleted Ubintu and installed Debian 9.4.0. And get the same situation. I have internet access and i don't have accsess to reps.

sudo command gets me this messages:

Ok, let's have a look at your software sources.

To readers of this thread in the future: note that although this is a Ubuntu subforum, and despite some commonality, this thread now refers to Debian software sources.

To the OP: why were you so quick to ditch Ubuntu? Was it because of the software sources problem?

Here is my sources.list file:
more /etc/apt/sources.list

# deb cdrom:[Debian GNU/Linux 9.4.0 _Stretch_ - Official i386 DVD Binary-1 20180310-11:55]/ stretch contrib main

yea... am i right i should move 'deb http...' and 'deb-src...' strings at the top of the file?


Directory /etc/apt/sources.list.d/ is empty.


>> To the OP: why were you so quick to ditch Ubuntu? Was it because of the software sources problem?
No.. of course not. It was some miserable issue that i moved to Debian. I use Ubuntu at my home computer with no any problems. I think both Ububtu and Debian are great distros.

From https://wiki.debian.org/SourcesList:

Also, comment out those cdrom entries unless you're still using an optical media device as a repository.

you need only either su or sudo.
this is overkill.

(the screenshot shows that op su'd to root first, then used sudo apt...)

This is current version of my sources:
#
# Repositories links
#

deb http://deb.debian.org/debian/ stretch main
deb-src http://deb.debian.org/debian/ stretch main

deb http://deb.debian.org/debian/ stretch-updates main
deb-src http://deb.debian.org/debian/ stretch-updates main

deb http://security.debian.org/debian-security/ stretch/updates main
deb-src http://security.debian.org/debian-security/ stretch/updates main


But problem is still exist. Maybe it connection issue, not reps. When I put address: 'http://deb.debian.org/debian/' in to the web browser it works fine, it shows me web page with debian folders.

I used (without sudo)
apt update && apt upgrate
under the root permissions... But I've got the same.

Can you please run another apt update to see what it gives.
