Guys I could really use a steer if someone has one for me. I am running Buster on the machine in question. Upgrading and using a usb3 antenna for ac internet speeds. I have this driver installed on several other buster machines and it is fast as hell. On this machine somehow, someway, I have caused a broken package. and the driver won't install. Let me paste in the terminal output below to see if you guys can give me a way to correct this scenario: attempted terminal install of libc6-dev after downloading from Debian mirror to my Desktop XXX@debian:~$ cd Desktop && sudo dpkg -i libc6-dev_2.28-10_amd64.deb [sudo] password for XXX: Selecting previously unselected package libc6-dev:amd64. (Reading database ... 235438 files and directories currently installed.) Preparing to unpack libc6-dev_2.28-10_amd64.deb ...

I have a crap load of personal modifications on this drive so avoiding a scratch reinstall would be highly preferable. Should a reinstall be required I may elect to stay with the older slower motherboard nics on this machine. A rebuild would be a solid day and a half at least. This Buster OS is running slick, updates great, and is flawless up until I decided to load the linux driver that comes with the antenna. Again, it works fine on my other Buster setups. Don't remember what I did that would cause the 2.29-2 version to be on this system. Ideas anybody? ps - Support for the driver (realtek) says ANY version of libc6-dev will work, so even some upgraded version of that would be fine.
