Since OpenVZ cannot be upgraded from inside of the VM's client (which I only rent). Is it possible to upgrade to 18.04 LTS from 16.04.5 LTS?
The problem lies on libc/locales
This version of libc requires kernel version 3.2 or later. Plase upgrade your kernel before installing glibc
tried to apt-mark hold libc6 and locales, the do-release-upgrade refuses to continue.
My VPS wasn't rebooted for about 3 months. It is hosted on a server with OpenVZ virtualization type and the operating system is Ubuntu 16.04. For some reason, I rebooted the VPS and after that, I couldn't connect to the server through ssh, the message that I received is:
ssh: connect to host srvname.com port 22: Connection refused
So I opened a Serial Console on the VPS and start investigating... I've purged and reinstalled the openssh-server with no success. I spent two hours reading articles, question, and answers about similar issues on Internet.
Finally I managed to understand that the directory /var/run/sshd is not created during the system startup. And once I create it manually I can start the SSH service without any problem, but on the next reboot the issue remains. So my questions are:
What could be the cause of this issue? Why /var/run/sshd is not created during the system startup?
How can I solve the issue in a proper way? I found a temporal solution that is mentioned at the end of this post.
Does the issue could be related to the OpenVZ host of the VPS? Should I ask the hosting provider to solve it?

The temporal solution:
I found that /var/run is a symbolic link to /run, I do not know why this is needed, but when I modified the content of the file /usr/lib/tmpfiles.d/sshd.conf from:
d /var/run/sshd 0755 root root
to:
d /run/sshd 0755 root root
everything goes well on system startup, the SSH service is started normally and I'm able to log-in via SSH.
I have got a question and hope that somebody can help me. I own a vServer on a OpenVZ basis (I hate the kernel limitation) and can't install Redis.
What do I do:
apt updateapt upgrade(I don't know if this is relevant, but this appears during the process:

After that I can't start Redis-Server (failed because a timeout was exceeded). What can I do to fix this problem? I saw many threads about redis in this forum, but the solutions didn't help me. Sorry for my bad english. Thanks in advance.
I upgraded my server installation form 11.04 to 11.10, then to 12.04 over ssh. All seems almost ok - but there is a small issue with glibc, which is messing up my apt.
I tried sudo apt-get install -f but it does not get what it needs. I am running in a OpenVZ virtual machine.
How can I fix my apt dependencies?
