Ferdi's questions

I want to mount a webfolder (NAS-storage) via the terminal. In the end I want to be able to open documents via 'Spyder3' (a python IDE) stored in the webfolder.

The manual of the host gives this command

mount –t cifs //nas.ads.mwn.de/<share_name> <mountpoint> -o username=<lrz-kennung>,domain=ADS 

I adapted it for my paths etc. to

sudo mount –t cifs //nas.ads.mwn.de/USER /media/ferdi/webdisk -o username=USER,domain=ADS,vers=2.1

this results in: mount: bad usage

I checked the package with:

 apt list cifs-utils

this results in: Listing... Done cifs-utils/bionic,now 2:6.8-1 amd64 [installed]

I'm not sure about the vers (the meaning and the correct usage). That is just what was written in the host's manual.

Ubuntu 18.04 - I'm rather new to Ubuntu.

I want to use Thunderbird with 'Lightning'.
I installed Thunderbird via the 'Ubuntu Software' - Thunderbird 60.3.0.
In the Add-ons Manager of Thunderbird it states, that Lightning is supported till Thunderbird 52.* I wanted to install Thunderbird 52.* actually downloaded version 60.3.0 as .tar.bz2. I opened (not installed) it directly in the folder, where I extracted thunderbird

 /home/ferdi/Downloads/thunderbird

Here in the Add-ons Manager downloading Lightning works well, no issues detected so far.

What I want is Thunderbird with Lightning installed properly as package, so that I can call it in the terminal and see it, when I use Super+a.
