[EN] VBox Guest Additions Installation Errors

[onepiece]

Hoping the community can help me get VBox Guest Additions installed without an error.

Tried to install VBox Guest addtions in the normal way (see below).  Got some errors but because of my limited knowledge of Linux, not exactly sure next steps from here.  Forum and web search showed similar issues but just couldn't apply the solutions to my situation.  I'm aware I'm using VBox Version 6 and not 7 but that shouldn't be a problem to my knowledge.  The Guest Additions iso is proper for my verion of VBox.  Thank you in advance for help and Happy New Year!

Here is what I entered and then the error log:

@d-virtualbox:/media/d/VBox_GAs_6.1.48$ sudo sh ./VBoxLinuxAdditions.run

Guest Additions 6.1.48

Are you kidding us? VBox 6.1.48 is ancient old and will never work on recent kernels!

[der_bud]

The changelog for 6.48 (https://www.virtualbox.org/wiki/Changelog-6.1#v48) states:

Code: [Select]

Linux Guest Additions: Added initial support for kernels 6.5 and 6.6So they cannot run with newer kernels.
I have a machine with old Windows and Virtualbox Version 6.50 on that Host. The Linux Guests inside are working more or less ok with recent 7.x guestadditions installed, so it could perhaps work for you to have 7.x additions in a VM running with 6.x VBox on the host, but not the other way round.

[onepiece]

Thank you to all for your thoughts.

I have so many VMs running so smoothly under VBox 6.x I'm afraid to rock the boat with an "upgrade".  That said, I might try the suggestion to load Guest Additions 7.x in the guest version of Siduction I'm running.  Thanks again to all.

You would also have to upgrade your VBox 6.x on the host as well as you just cannot upgrade the guest additions in the guest alone.

Ugh, that's a compiler mismatch.  The Guest Additions are trying to use a slightly different GCC version than what built your kernel.  Happens more often than you'd think.  Try this:  see if you can find a package for the exact GCC version your kernel was compiled with (gcc-14 (Debian 14.2.0-11) in your case) and install it before trying the Guest Additions again.  That might fix the incompatibility.  If not, you might need to rebuild your kernel (not fun, but sometimes necessary).
