This board requires newer software error when installing MotionEyeOS on Raspberry Pi 4
I am currently testing MotionEyeOS on my test Raspberry Pi 4. I received an error “This board requires newer software” and the board goes into a reboot loop as per the below screenshot after I flashed the SD card with MotionEyeOS version motioneyeos-raspberrypi4-20200606 After some digging I found this post where user starbasessd pointed to the solution of installing the dev version (dev20201026). I downloaded and flashed the Dev version and successfully booted into MotionEyeOS

ESET NOD32 for Linux needs the following packages to install: libc6-i386, /lib/ld-linux.so.2
I tried to install ESET Antivirus on one of my machines and received an error stating: “ESET NOD32 for Linux needs the following packages to install: libc6-i386, /lib/ld-linux.so.2“ I had to install libc6 but just running an apt install libc6 showed that I already had libc6 installed. After some head scratching I noticed the -i376 (doh!) and installed the missing dependency using: sudo apt install libc6-i386 which resolved the issue and I was able to install ESET Antivirus.

Permission denied when uploading in Arduino IDE (Linux)
I very recently started playing with Arduino building different circuits etc. But my latest project was building a button box for sim racing, other driving and flight simulator games.

I am using a flatpak version of Arduino and after some searching I found the solution on this forum. Thanks to user tf68, as per his/her advise the below…

Unable to browse samba shares when internet connection is down
We’ve been having a lot of outages on our internet connection and I noticed that we are unable to browse the samba shares on our CentOS 7 server. After some searching on the internet I saw a few comments around adding the server’s host name and IP in it’s own hosts file. I proceeded to open /hosts/etc and added the IP and server name to the hosts file. Sure enough I could now browse my samba shares on the server with our internet being down.

free/busy not working between EOL and on premise Exchange
We had an issue after adding a new domain to our tenant using the Hybrid Configuration Wizard which removed the URI and URL strings in the availability settings in Exchange Online. That was resolved but 2 days later free/busy from Exchange Online to on premise Exchange users broke again. We had to add a new SAN in the certificate for Exchange and suspect that the Federation Metadata did not properly update. One of my colleagues found this article which pointed us to the problem and advised us how to resolve the issue. In short running: Test-FederationTrust -UserIdentity yourcredentials showed the issue. To resolve my colleague ran: Get-FederationTrust |…

Installing Manjaro
I started using Manjaro on my laptop and found that installing applications and using it differs quite a bit from the Ubuntu distributions that I am used to. I started this mini series to show how to use it, install the OS, install applications and show off some features I found that works great. The below video shows the installation and some features of Manjaro using the Gnome desktop environment.
