The problem showed itself when I executed apt-get update and it failed when trying to update gitlab-ce repository with following error (although it just did work about a month ago):

W: Failed to fetch https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/dists/xenial/InRelease  Operation timed out after 0 milliseconds with 0 out of 0 bytes received

then I tried curl to see the same URL and again it failed with following message:

curl -vvv https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/dists/xenial/InRelease
*   Trying 54.153.54.194...
* Connected to packages.gitlab.com (54.153.54.194) port 443 (#0)
* found 148 certificates in /etc/ssl/certs/ca-certificates.crt
* found 600 certificates in /etc/ssl/certs
* ALPN, offering http/1.1
* Operation timed out after 0 milliseconds with 0 out of 0 bytes received
* Closing connection 0
curl: (28) Operation timed out after 0 milliseconds with 0 out of 0 bytes received

but the funny thing is when I try to open the same URL using Firefox from the same system, it just works, although it redirects to another URL, but it works. The redirection target is something such as

https://packages-gitlab-com.s3-accelerate.amazonaws.com/7/8/ubuntu/dists/xenial/InRelease?AWSAccessKeyId=AKIAJ74R7IHMTQVGFCEA&Signature=Dwkp3C7Q2mXBtiPCUiFZhoGzWF8%3D&Expires=1529707236

What can I do to fix the problem and make apt-get update work again.

The result of curl -V:

curl 7.47.0 (x86_64-pc-linux-gnu) libcurl/7.47.0 GnuTLS/3.4.10 zlib/1.2.8 libidn/1.32 librtmp/2.3

My Linux system has two users, and I configured samba on it, so some shared directories are accessible by both uses, and some are accessible by one of them.

The problem is when I access the computer from Windows clients and authenticate using the second user (with less permission), the folders which are not accessible are shown (although they are not browsable), how can I hide these folders from this user?

Here is a part of /etc/samba/smb.conf file:

[anonymous]
    path = /repo/samba/anonymous
    writeable = yes
    browseable = yes
    valid users = user1, user2

[archive]
    path = /repo/samba/archive
    writeable = no
    browseable = yes
    valid users = user1, user2

[user1]
    path = /repo/samba/user1
    writeable = yes
    browseable = yes
    valid users = user1

[user1-ro]
    path = /repo/samba/user1-ro
    writeable = no
    browseable = yes
    valid users = user1

When user2 tries to access the server, they see user1 and user1-ro folders too, and I want to hide these two for them.

I shall mention that the linux system runs Ubuntu-MATE 16.04.

I want to access a computer with Ubuntu-MATE 16.04 from my laptop (running Windows 10). I can use SSH and access it in terminal mode, but sometimes I need to access it using GUI.

Years ago there was a computer in my office running Ubuntu 10.04 which I had remote GUI access to using XManager 4 without any problem, and I am looking for the same experience on the new system with Ubuntu-MATE 16.04.

I've tried to use MobaXterm as a free alternative to XManager 4, I can access the system in terminal mode but have no success in GUI mode.

I also installed xrdp on the system, and then connected to it using Remote Desktop, but as my laptop gets a 4K display, the screen lagged and font sizes where so small and un-readable.

So what are the alternative solutions, and how can I access this computer from Windows 10 in GUI mode?
