Docker and omv-extras doesn't work.

Greetings everyone !

Few days ago I've installed and configured OMV on my old laptop. It went smooth, nice and without absolutely any issues. I was so happy OMV user I decided to make it working allso as a cloud, so....

1) I watched full video about docker and all extras from Techno Dad Life - just from this link:

2) After installing putty and loging as a root on my server machine, I've copied a link from omv-extras.org and it went smooth, installation finish without any issues.
3) Here is where the problem occurs: after refreshing page, OMV-Extras did NOT appear in my menu. I tried to reboot machine but it didn't help.

4) I went back to omv-extras.org and I went to installation through GUI section. I've downloaded a 5th version package , uploaded by GUI, in Plugins section and openmediavault-omvextrasorg-5.4.2 appear on my plugins list. When I checked it and tried to install it I've recieved an information this plugin can not be installed because somethink went wrong.
5) This is error message:

6) I didn't modify any files on server machine or anythink with GUI - everythink is just OEM, like installed with OS.

7) I allso doesn't see flashmemory update on the list...

8 ) Copying link with -wget from website and installing it again doesn't help Installed successfull again...

9) My OMV version: 5.5.13-1 (Ursul)

10) Plzz help

Doesn't help, I was login on my phone and still have nothink new in menu.

That's what i get while i paste it as root/putty:
2nd pic is printscreen from my GUI.
As I sayed, link from omv-extras, pasted as a root, install everythink successfull... just without any difference at menu.

PS thank You very much for trying to help me. I'm realy bad at linux 🙁

Unfortunately thoose 2 commands didn't help. Nothink changes BUT I found somethink interesting in installation, take a look at the screens. (They are in polish but I made some translations and I left some marks. Thoose screens are from complete installation"

Wymaga: means required
Ale nie da sie go zainstalować: means but it was impossible to install

Nastepujace pakiety maja niespelnione zaleznosci: means Following packages has not fullfiled variables

Ryecoaaron - You are my true hero today! It allso worked for me ! Thank You so much

I have one more question because I am not quite sure of my own lack of knowledge of omv malfunction.

When I first time install omv os, during creating shared folders, I left priviges only read and write for admin, all users and guests was as no access. Then I grant some users prividges and I couldn't see/enter thoose folders anyway. I was strugling with it half of the night, at the end I wiped whole hdd and I've made a new clean install of Omv os; the same installation I'm using till now.

When I was creating new shared folders, I tried to set write/read option for admin AND for users. Guests stayed with no access. Then I configure access or limitations for specific users in shared folders menu and allso in users menu. Everythink worked well, without any issue... Till now:

I've started to installing omv-extras, duckdns and nextcloud. During installation of thoose extensions I was adding shared folders for files, separately for nextcloud, duckdns etc. All folders has been created with access and write /read options for admin AND users. No access for guests. Immediately I was allso configurating access options in users menu and shared folders menu.

This time when I've entered my omv shared folder location, on my windows machine, I was unable to see new folders. Even when I typed direct path to the location I was unable to open folder and I recieved error message about path doesn't exist or i have no access. I'm sure user id and pw I've used for login got all access granted.

While ssh->root i can see thoose folders exist with all content.

Does anybody know why does it happening? How can I fix it?

I'm sorry, that was my lack of knowledge, accualy I forgot to make share in SMB/CIFS. Thank You very much for all Your time, patience and help. I realy apreciate.
