macos installation couldnt be completed from 10.13.6

My macbookpro is a year old, and has never had a problem till now. Just tried to update it, but it wont bootup after. I tried booting in safe mode, but this didnt help. I was able to boot of the main “drive”,

The log files have lines like this:

- Failed to open file <private> [2: No such file or directory] - The main OS Installer distribution (/Volumes/Macintosh HD/Library/Updates/AtomicUpdates/041-53308/041-53308.English.dist) did not load with error: The file doesn’t exist. - Folder Manager is being asked to create a folder (down) while running as uid 0 

I have read there are a few options:

  1. reinstall OSX. This sounds too drastic.
  2. try doing the update again?

Suggestions?

What mutex is apache trying to lock when the error “Couldn’t grab mutex” is logged?

Apache 2.4 suddently dies in a fresh ubuntu 18.04. Certbot installed. Certificates authorized manually and installed manually (certbot did not touch my files). The logs are these:

In fact, there are plenty of forums that suggest changing the Mutex mechanism in the configuration. For example this one:

https://stackoverflow.com/questions/50652808/apache-shutdown-couldnt-grab-mutex

But before applying any magic I want to:

a) Understand what file apache is trying to lock. b) eventually force to repeat the error (I want you apache to do it now) so I can provoke de crash.

Question:

How can I know what file is apache willing to lock when it says “couldn’t grab the accept mutex”?

Asus X550V couldnt install ubuntu

I’ve tried million times installing ubuntu on my dekstop and always fail with screen freeze after log in to dekstop (try without installing ubuntu) and installation page pop up (install ubuntu). I’ve searched lot of forum which mention same problem and couldnt find a solution about this. Did this happened because my NVIDIA Geforce GTX 950M? But i have tried disabling it and the result still the same. Could someone help me to solve my problem about this? Because i really need ubuntu for my research. Or my laptop could never support ubuntu basically? Thank you for ur help

fcntl couldn’t lock /dev/null and hang

A minimal working example, but only for my machine:

int main(int argc, char* argv[]) {     int fd = open ("/dev/null", O_RDWR|O_CREAT);   if (fd < 0) {     printf("Failed to open file\n");   }    struct flock lock;   lock.l_type = F_WRLCK;   lock.l_whence = SEEK_SET;   lock.l_start = 0;   lock.l_len = 0;    int res = fcntl(fd, F_SETLKW,&lock); // this hangs   if (res < 0) {     printf("Failed to lock\n");   }   close (fd);   return (0); } 

The program above hangs only on my machine, and completed instantly on 7 other machines. Is there anything that I can look into to investigate this problem?

How to change assembly directory ? VS Couldn’t find assembly in the folder

I’m trying to create a program for a Thermal Printer.

I download a Hello World example from Intermec Website.

But when i try to run it say :

/Library/Frameworks/Mono.framework/Versions/5.20.1/lib/mono/msbuild/15.0/bin/Microsoft.Common.CurrentVersion.targets(5,5): Error MSB3073: Command “mono c:/Intermec/SmartPrintingRK/Utils/FtpPut.exe HelloWorld.exe ftp://10.203.33.124/apps/HelloWorld.exe user pass” stop with code 2. (MSB3073) (HelloWorld)

I try to remove and add again assembly but without any success.

‘c:/Intermec/SmartPrintingRK/Utils/FtpPut.exe’: No such file or directory.’ But i’m on a mac so sure you couldn’t find file … How to change it ?

Sitemap “Couldn’t fetch” in Google Search Console

I’ve submitted a sitemap to my website and Google Search Console status is “Couldn’t fetch”. I’ve had my xml verified by XML Validation, and my xml is also publicly available to be viewed: https://simplyharmonica.com/sitemap.xml. Google’s support website suggested troubleshooting “Couldn’t find status” with the url inspection tool. I wasn’t able to find anything useful from that asides that https://simplyharmonica.com/sitemap.xml hasn’t been crawled.

Error when opening .docx file from SharePoint – “Sorry, we couldn’t open (…)”

We are unable to open some .docx documents in Word desktop application from an on premise SharePoint 2016 document library. There are at least 2 of such documents, but might be more.

The error message in Word is:

Sorry, we couldn’t open http://filepath

The file opens in Word Online, but only in read mode – if I try to switch to Edit mode, there’s an error.

It works perfectly fine if I just download it and open in Word. Many (possibly All) users are affected.

What I already tried:

  • Deleting OfficeFileCache
  • Opening from different browsers
  • Opening directly from Word (file->open)
  • Uploading a new version of the file (download->edit->upload)
  • Opening the file from a server where an older version of Word 2016 is installed
  • Running full crawl, reindexing the library

-If I download the file and then upload it with a different name – it opens fine. But that’s not a solution because we need version number and version history.
-If I download the file, delete the original from sharepoint and upload it with the same name – it won’t open

Our Word version is 1809 (O365)

Would you see any other solutions? Thanks!
