I have an own linux server (ngnix, gunicorn, python flask) connected it via dyndns to my frtizbox and to my domain and dyndns provider (selfhost.de). Now I would like to connect to this linux server using ssh like this:

ssh [email protected] 

This means not with the ip addr cause this is changing in case of power breakdown or frit box restart.

I saw that there are services like ddclient. I set this service up but I do not know how to connect now using the above command: I still get this error:

ssh: connect to host domain_name.de port 22: No route to host

OS:

• Ubuntu server: 20.04 LTS
• Ubuntu Laptop I want to access the server with has: 18.04 LTS

Details: If I have both machines in the local network I already can access via:

ssh server_name@192.....

Next I tested with both machines having the same local network to connect with publich ip:

ssh [email protected]......  --> Error no route to host 

I then allowed port 22 at my fritzbox and it worked!

Is this issue related to that both machines have the same public ip?

Next I tested to have my laptop in other network (hotspot with mobile phone)

ssh [email protected]......  --> Error no route to host 

Finally I want to achieve above with domain name....

I then allowed port 22 at my fritzbox and it worked!

I also stopped now my ddclient: sudo service ddclient stop

and I still can access using

ssh [email protected] 

Do I need ddclient at all?

Hey there I tried to install latex using the follwing commands in ubuntu 16.04:

sudo apt-get install texlive-full texstudio

Then I finally came to the point with the following output:

Setting up thunderbird-locale-en (1:52.3.0+build1-0ubuntu0.16.04.1) ... 
Setting up thunderbird-locale-en-us (1:52.3.0+build1-0ubuntu0.16.04.1) ... 
Setting up context (2015.05.18.20150601-2) ... 
Running mtxrun --generate. This may take some time... done. 
Pregenerating ConTeXt MarkIV format. This may take some time...

And after waiting for 5 hours I closed the process. Unfortunately now my certain packages seem to be broken. e.g when I try to install a new package or try sudo apt-get dist-upgrade I get the following error:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure
-a' to correct the problem.

And If I try

sudo dpkg --configure -a

I came again to the endless waiting point....

Any Ideas what I can do?

Notes:

• I also have installed Miktex before does that cause some troubles?

• I unfortunately cannot remove any package cause I also get:

   sudo apt-get remove tex-common
   E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
