debian – Networking start failed on OVH Proxmox 6.4 if a bridge has no interface

We are setting up a new Proxmox 6.4 (based on Debian 10.9) host on OVH (Avance-2) hardware, using the OVH provided template.

In order to create a “virtual” bridge for VMs and LXCs, we added these lines into /etc/network/interfaces :

auto vmbr1
iface vmbr1 inet static
        bridge-ports none
        bridge-stp off
        bridge-fd 0

This configuration works fine on all our Proxmox hosts, but fails on the new machine: reboot takes 20 minutes on “Starting Raise network interfaces”, fails with “Failed to start Raise network interfaces” and the bridge interface is not up.

After rebooting without the vmbr1 stuff, I could see that systemctl restart networking hangs on “Starting to wait for vmbr1 link to be up”

google sheets – How to start the script from the third row for dependent drop down list?

I am NOT expert in coding, just managed to piece together a script with dependent drop down list.
The script is to allow user to select the drop down list from Row 1, Column B, C, D, … (eg. B1) with dependent drop down list (eg. B2, B3, B4, B5). Similarly for Row 6, 11; Column B, C, D, ….
However, the script doesn’t work when I insert two rows above Row 1 as I would want the first and second row for date and time.


Below is the script that works if everything start from Row 1.

function onEdit() {
  var tabLists = "Lists";
  var tabValidation = "Main";
  var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var datass = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(tabLists);
  var activeCell = ss.getActiveCell();
  if(activeCell.getRow() % 5 == 1 && activeCell.getColumn() > 1  && activeCell.getColumn() < 10  && ss.getSheetName() == tabValidation){
    activeCell.offset(1, 0).clearContent().clearDataValidations();
    activeCell.offset(2, 0).clearContent().clearDataValidations();
    activeCell.offset(3, 0).clearContent().clearDataValidations();
    activeCell.offset(4, 0).clearContent().clearDataValidations();
    var makes = datass.getRange(1, 1, 1, datass.getLastColumn()).getValues();
    var makeIndex = makes(0).indexOf(activeCell.getValue()) + 1;
    if(makeIndex != 0){
        var validationRange = datass.getRange(3, makeIndex, datass.getLastColumn());
        var validationRule = SpreadsheetApp.newDataValidation().requireValueInRange(validationRange).build();
        activeCell.offset(1, 0).setDataValidation(validationRule);
        activeCell.offset(2, 0).setDataValidation(validationRule);
        activeCell.offset(3, 0).setDataValidation(validationRule);
        activeCell.offset(4, 0).setDataValidation(validationRule);

Any advice on how to make it works if I would like to add two more rows above Row 1?

networking – kube-proxy won’t start in Minikube because of permission denied issue with /proc/sys/net/netfilter/nf_conntrack_max

After updating Arch Linux (sudo pacman -Syu) and restarting the system, Minikube fails to start because of kube-proxy. The logs show it was trying to modify /proc/sys/net/netfilter/nf_conntrack_max but it ran into a permission denied issue.

I tried to run sudo chmod 777 /proc/sys/net/netfilter/nf_conntrack_max but the system didn’t allow me. I also removed ~/.minikube and started again, but it still refused to work. Same issue when starting kind. Can anyone tell me how to fix this?

windows – Hyper-V VMs fail to start: “the specified module could not be found”

I’ve got a standalone Hyper-V virtualization host running Windows Server 2019. Since the last time we’ve restarted it, a handful of its VMs refuse to start with an error I can’t quite figure out. They’re stuck in the off state.

Error message

The same four errors are thrown for all of the affected VMs. I’ve found nothing when trying to search for a better explanation of what’s going on; any ideas how I can resolve this?

In Which European Countries Is It Best For A Foreigner To Start A Business?

There are many countries in Europe that have good conditions for foreign investment and which offer excellent opportunities for foreigners who want to start their business in this country. You shouldn’t focus only on the large countries of Europe. Smaller countries sometimes offer more lucrative options. For example, I know that anyone have a chance to get government support if you want to start an environmentally friendly business in Monaco. In this article…ness-in-monaco/ are more detailed info. I think this country has everything you need for a successful business.

How/where to start my blog?

I’m starting a blog which I hope to eventually monetize.

In fact I’m considering beginning multiple different blogs in the hopes of finding one to monetize. I’m hoping to start with a free blog website in case my blogs aren’t gaining traction or if the content is too hard for me to create over the long term.

Which site do people suggest I use?

My concern with a free blog site is, the difficulty transferring content to a domain I eventually purchase, when it’s time to monetize the blog.

Does anyone have experience with moving a site from a free blog to a site where you can monetize the blog? Can you offer any advice?

flutter – How to Start itemCount in ListView.builder from where previous list left off?

I have 2 rows of Listview builders (scrollable horizontally) showing interests.

Hoping that the first row will show the first 6 interests, and the next row showing the rest on the list.

How do I make the itemCount in the second as a range from 7 all the way to the end?

Any help is appreciated. The snippet of the code is as follows:

                      padding: const EdgeInsets.fromLTRB(6, 6, 0, 0),
                      child: Container(
                        width: MediaQuery.of(context).size.width,
                        height: MediaQuery.of(context).size.height * 0.045,
                        child: ListView.builder(
                            shrinkWrap: true,
                            scrollDirection: Axis.horizontal,
                            padding: const EdgeInsets.all(1),
                            itemCount: 6,
                            itemBuilder: (context, int index) {
                              return Interests2(AvailableInterestChosen(
                                isChosen: false,
                      padding: const EdgeInsets.fromLTRB(6, 3, 0, 0),
                      child: Container(
                        width: MediaQuery.of(context).size.width,
                        height: MediaQuery.of(context).size.height * 0.045,
                        child: ListView.builder(
                            shrinkWrap: true,
                            scrollDirection: Axis.horizontal,
                            padding: const EdgeInsets.all(1),
                            **// itemCount: allInterests range from 6 to end of list,**
                            itemBuilder: (context, int index) {
                              return Interests2(AvailableInterestChosen(
                                isChosen: false,

The bold part in the 2nd padding is where I’m having trouble building the range.
