20.04 – VDI – Failed to Start System Security Services Daemon

I am trying to up a VDI imagem from osboxes (Ubuntu 20.10 or 20.04) with oracle virtualbox (v. 6.1.18).

The problem occurs when the Ubuntu is loading. I posted a image pointing the error. I saw some other posts in here suggesting disable the sssd.service through systemctl but I am not able to to that because I can’t get there – in the OS interface.

So, is there something that I should try?

Thanks in advance!

backup – DPM 2019 Synchronization failed: (ID 65 Details: An existing connection was forcibly closed by the remote host (0x80072746))

I am using a System Center 2019 DPM as a backup server that is running on its own hardware. Besides other backups, it backs up files from a file server cluster.

The file servers use a deduplicated volume to store the files. The backup job backs up a folder on that volume and not the entire drive. During scheduled synchronization – sometimes (not always) – the following error occurs:

The DPM service was unable to communicate with the protection agent on <THE_BACKUP_SERVER_ITSELF>. (ID 65 Details: An existing connection was forcibly closed by the remote host (0x80072746))

The error resolves itself automatically with the next scheduled synchronization on the next day, or by another self initiated synchronization (by the job itself).

How can I prevent this error from happening at all? It is strange that the error occurs when the backup server is performing a backup on another machine, but is having problems to communicate to the protection agent that is running on the backup server itself.

virtualmin – Failed to create virtual server : The domain x already hosted by your Apache webserver

I’m just trying to create a new virtual server, unfortunately it does not work.

I created a virtual server and deleted it.

I’m trying to create a virtual server with the same name, but I get this error message:

Failed to Create Virtual Server: The Domain X is Already Hosted by
Your Apache Web server.

I have searched for a solution and have only found a question regarding this problem with the solution to delete the alias from the virtual server in httpd.conf file, but I do not have this file and in apache2.conf I do not find the alias from the Virtual Server .

rom flashing – Samsung bootloader unlock but failed to flash custom rom

I go to Settings > About Phone > Software Information then tap the Build number 7 times to enable Developer Options.

Then I connected my device to the internet and go to Settings > Developer Options > OEM Unlocking set to Enabled to unlock the Bootloader, (the phone is reset to data factory but the OEM Unlocked says it’s already enabled after that).

Now I want to flash a custom ROM, but I failed to do so and the error in download mode says Only official binaries are allowed to be flashed. I think this is somehow related to Bootloader which is not fully unlocked. Is there anything I should do before flashing custom ROM?

I’m actually trying to root my device and I’m following this tutorial.

c++ – LookupAccountNameW returning Failed (0x534) when user log on via Azure

I am running this code:

LookupAccountNameW(NULL, (LPCWSTR)UserName.c_str(), NULL, (LPDWORD)&UserSIDSize, NULL, (LPDWORD)&DomainNameSize, &SidType);

But noticed that when the user is an Azure user, it will returns:
1332 (0x534)

Again this issue is not seen if the user is local or part of an attached domain. Did I do something wrong, or am I missing something?

dnd 5e – Does the 3rd benefit of the (UA) Fizban’s Platinum Shield spell stack with Evasion, so that the character only takes 1/4 damage on a failed Dex save?

The new UA, Unearthed Arcana: Draconic Options, introduces a 6th-level spell called Fizban’s platinum shield that can be cast on a creature within 60 feet of the caster, granting them a few benefits. The description of the final benefit reads as follows:

  • If the creature is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, the creature instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

This has the same effect as the Evasion feature of a Monk or Rogue (or Hunter ranger, maybe).

Since this spell benefit and Evasion have the same effect but different names from different sources, would they stack with each other?
For instance, in the case of a 7th-level monk failing a Dex save against the fireball spell while under the effect of this spell, would they take a quarter damage?

postfix – Trouble enabling mail_crypt in dovecot / SASL authentication failed

Ok, I tried to enable mail-crypt but it’s being weird. I’m using https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/#ec-key.

I ran:

cd $HOME
openssl ecparam -name prime256v1 -genkey | openssl pkey -out ecprivkey.pem
openssl pkey -in ecprivkey.pem -pubout -out ecpubkey.pem

I edited the dovecot config to:

. . .
mail_max_userip_connections = 120
. . .
mail_plugins = $mail_plugins mail_crypt
plugin {
  mail_crypt_global_private_key = </home/ec2-user/ecprivkey.pem
  mail_crypt_global_public_key = </home/ec2-user/ecpubkey.pem
  mail_crypt_save_version = 2
. . .

I see in the logs now:

I wonder why SASL is now enabled for postfix to work/authenticate (when it’s not if I turn off mail_crypt).

I’m guessing Server configuration problem is the problem here…

Any suggestions where I should look?

ERROR IN in my SPFX WebPart : Module parse failed: Unexpected token You may need an additional loader to handle the result of these loaders

I have created an SPFx project with reactJS. I am using .jsx extension – functional components.

Now, the spfx webpart is already working fine, but I saw a material kit that I want to reuse its components.

When I referenced the components, I am presented with this error

***Failed to load component (WebPart). Original error: ***Failed to load entry point from component WebPart). Original error: Module parse failed: Unexpected token (30:4)
File was processed with these loaders:
You may need an additional loader to handle the result of these loaders.

It seems that I cannot use the “footer” tag?
