Problem by installing yunohost

Hello,
Can someone help me. I have a VPS and tried to install yunohost on it, via the Terminal. I have no knowledge of programming, but followed the instructions on the webpage. So I became root. That was not a problem. Entered the command for installing yunohost. “curl https://install.yunohost.org | bash” This started. Got two questions, both answered with Yes. After that I recall to have seen a mention of a failure, if I remenber well it was about the library. Unfortunately I haven’t made a screensave. I was to eager to go further. So I typed the IP adres in my browser and then … instead of the yunohost page, I got the welcompage of nginx.


So something went wrong.
I tried to start again, installing yunohost as I did before. Became root. This I can still become. Gave the command for installing yunohost, and then I got the message that I was doing an update and that it failed to do so:

```  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

[INFO] Installation logs are available in /var/log/yunohost-installation_20200510_145225.log

I don't know how to view the log and I'm afraid it won't make me much wiser.
What can I do now? 
Very grateful if someone can help me.

You can view the log with this command:
$ cat /var/log/yunohost-installation_20200510_145225.log
But tell us, what kind of VPS are you using ?
Is you’re server a Debian 9 Strecht OS (Yunohost is not running on Debian 10 Buster for now) ? Have you before run an update ?
$ apt update && apt upgrade
What is your sources.list, to see it :
$ cat /etc/apt/sources.list

TODO before:
Perhaps it is better for you to install a sudo user on you’re VPS and to configure the sudo user to be avalaible to connect by ssh you’re server and so not use the root account to do it …
Some details here can help you: https://www.digitalocean.com/community/tutorials/initial-server-setup-with-debian-9

thanks for your reaction.
I don’t know which Debian version is installed, it is Debian, so far I know. how can I see this?
No I haven’t run an update before. I just started.
I now have viewed the log, do you want to see it?

My source list:

# deb http://mirror.transip.net/debian/debian stretch main

deb http://mirror.transip.net/debian/debian stretch main
deb-src http://mirror.transip.net/debian/debian stretch main

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

# stretch-updates, previously known as 'volatile'
deb http://mirror.transip.net/debian/debian stretch-updates main
deb-src http://mirror.transip.net/debian/debian stretch-updates main

Ok, you are with a Debian 9, it is good.
But I think you must add repositories in your sources.list. You can edit it with this command (on root user):

nano /etc/apt/sources.list

and change the lines like this:

`# deb http://mirror.transip.net/debian/debian stretch main

deb http://mirror.transip.net/debian/debian stretch main contrib non-free
#deb-src http://mirror.transip.net/debian/debian stretch main contrib non-free

deb http://security.debian.org/debian-security stretch/updates main contrib non-free
#deb-src http://security.debian.org/debian-security stretch/updates main contrib non-free

#stretch-updates, previously known as ‘volatile’
deb http://mirror.transip.net/debian/debian stretch-updates main contrib non-free
#deb-src http://mirror.transip.net/debian/debian stretch-updates main contrib non-free`

and then do an update and upgrade (with root user) with:

apt update && apt upgrade

… Let’s not speculate on what’s the issue and let’s look at the log first …

… Just run the cat command suggested by rodinux in the first answer …

cat /var/log/yunohost-installation_20200510_145225.log

here’s my log, and thanks for looking at it:

Can you trythis, run:
dpkg --configure -a
It seems there was a problem with the package ssl-cert. What happens if you try run this:
update-ca-certificates

I’ve run

dpkg --configure -a

I got this: > root@xxx-xxx-xxx-xxx:~# dpkg --configure -a

after that i’ve tried to run as you said:

Can you try run
apt install -f

of course I can
unfortunately I again got the same error

It really looks like it’s an issue in ssl-cert’s postinst script … But I can’t reproduce the issue on my side whatsoever …

Can you tell where you bought that VPS ?

Alternatively we can try to find why it’s not happy about the sed commands but that’s a bit technical …

I would run :

cd /root/
apt download ssl-cert
dpkg -e ./ssl-cert*.deb
grep -nr "sed" DEBIAN/postinst

I doubt is perhaps a problem with your sources.list. I wait before with @Aleks recomandantions…

I got the VPS via Waag.org on an information evening sponsored by www.transip.nl, I can use the VPS for 3 months, some people got through the installation, others like me not, at the Waag they couldn’t help me

I hope I have done this right, I just copy past the whole thing and got this:

‘’'root@xxx-xxx-xxx-xxx:~# cd /root/
root@xxx-xxx-xxx-xxx:~# apt download ssl-cert

root@xxx-xxx-xxx-xxx:~# grep -nr “sed” DEBIAN/postinst

Hm sorry my last command was buggy, not sure why but can you retry to launch just :

cat DEBIAN/postinst | grep sed

(Edit: ah in fact it’s some weird issue about using “ instead of " (different type of quote) ? … but whatever)

(and yes my fault, got the wrong " … now I’ve got the right one, I hope)

	     "$(openssl x509 -issuer -noout < ${CERT} | sed 's/issuer= //')" = "$(openssl x509 -subject -noout < ${CERT} | sed 's/subject= //')" ]; then

Hmokay so what happens if you run

CERT=/etc/ssl/certs/ssl-cert-snakeoil.pem
echo $(openssl x509 -issuer -noout < ${CERT} | sed 's/issuer= //')
echo $(openssl x509 -subject -noout < ${CERT} | sed 's/subject= //')

this:

root@xxx-xxx-xxx-xxx:~# echo $(openssl x509 -issuer -noout < ${CERT} | sed 's/issuer= //')
-su: /etc/ssl/certs/ssl-cert-snakeoil.pem: No such file or directory

root@xxx-xxx-xxx-xxx:~# echo $(openssl x509 -subject -noout < ${CERT} | sed 's/subject= //')
-su: /etc/ssl/certs/ssl-cert-snakeoil.pem: No such file or directory

Alright so that’s not the issue …

What happens if you run :

make-ssl-cert generate-default-snakeoil

this:

sed: -e expression #1, char 47: unterminated `s' command

Hmokay so that’s closer to the issue …

Does the command 'hostname' returns anything ? (Sorry I know that’s a bunch of weird questions)
