Looks like you're not connected to the network/internet.

It is not problem with Internet/network, because My Academy Dspace 6 repository has access to Internet, that is I can make access to it through Internet from any computer.

Ubuntu 18.04 LTS reached end of life 6 days ago so I think that what's causing the issues you are facing. Definitely you need to upgrade to a newer Ubuntu version that still supported or as another option you can buy an extended commercial support for the 18.04 version you have to keep using it for a while but still the right decision is to upgrade both the OS and dspae since dspace 6.x will reach end of life too in less than a month from now.

I have Ubuntu 18 LTS and Dspace 6 on another computer which is temporary web server and not real web server. And I have not any such problem which I described above.

It's an OS issue and for sure it's fixable but without more in-depth details I'm shooting in the dark. Trying to help. Try the steps you see below in the sequence you see it:

1) sudo truncate -s 0 /var/lib/ubuntu-release-upgrader/release-upgrade-available

2) sudo dpkg-reconfigure dash

** make sure to choose no when prompted if you want to (Use dash as the default system shell).

3) ping changelogs.ubuntu.com (make sure if it's resolvable.). If for any reason it can't be resolved double check your DNS settings in /etc/resolv.conf. You can use google public dns server 8.8.8.8 temporarily.

4) sudo shutdown -r now

5) apt update -y && apt upgrade -y && shutdown -r now

6) You have to upgrade your server to a newer version. You need to.

Hope it helps.

In addition to the previous message and after completing it. it's possible the cause of the issue you have is the failing of the start of Network Name Resolution so you need to further check why it's failing. You can check the service log or the it's errors by running the following comands.

To check the service log.

1) sudo journalctl -u systemd-resolved

To check the service errors it generated.

2) sudo journalctl -u systemd-resolved -p err

To override it temporarily.

3) cp /etc/resolv.conf /etc/resolv.conf-orig && echo "nameserver 8.8.8.8" > /etc/resolv.conf

Update & Upgrade your server.

4) sudo apt update -y && sudo apt upgrade -y && sudo shutdown -r now

Hope it helps & Good luck

Mo.

Error 1: String “resolv.conf->../run/system/resolve/stub-resolv.conf” is colored by red color.
Error 2: File “stub-resolv.conf” does not exist.

Question 1: Should I restore “stub-resolv.conf” and symbolic link “resolv.conf->../run/system/resolve/stub-resolv.conf”?

>make sure that your DNS and gateway configurations are correct.

>Also check that systemd-resolved.service is started - sudo systemctl status systemd->resolved.service

Error 3: Systemd-resolved.service loaded, but failed.

sudo systemctl start system-resolved.service – failed.

Result of “sudo systemctl start systemd-resolved.service”:


Result of “journalctl -xe”:

Question 2: Should I make that systemd-resolved.service will be started that is to be active?

I hate to be "that guy", but this seems pretty clearly a networking issue with Ubuntu, and nothing related to DSpace.  I think the question is probably best asked elsewhere, and not just because it isn't related to DSpace, but because you'll likely get more and better responses from a support channel that's dedicated to Ubuntu.

Could you please recommend a support channels  that's dedicated to Ubuntu?
