+ [Original bug report]
Still trying to find causes, but this sympton:
for a 25.10 guest image, the virtualbox guest additions install
(VBoxLinuxAdditions.run from the official ISO) fails checksum. The
Linux installer script is a makeself self-extracting archive (makeself
is a Ubuntu package, though I don't know if the VirtualBox team uses
Ubuntu to generate the archive). The output of trying to run this script
is:
# ./VBoxLinuxAdditions.run --noexec
Verifying archive integritiy... 100% Error in MD5 checksums:
c8ea742682d7024e581f916c763818c9 is different from
201ccc47587bb1c28745279e8b7fdd30
The 201ccc signature is the one embedded in the script. On a 25.04
system, there is no checksum complaint:
# ./VBoxLinuxAdditions.run --noexec
Verifying archive integrity... 100% MD5 checksums are OK. All good.

+ Uncompressing VirtualBox 7.2.2 Guest Additions for Linux 100%
I was sure this was due to the switchover of the waste-of-time coreutils
rust rewrite (please ignore the editorial comment!)... but copying over
coreutuils md5sum from 25.04 does not eliminate the error.
Tar on both systems is 1.35.
md5sum on today's (23 Sep) 25.10 reports: md5sum (uutils coreutils) 0.1.0
on 25.04 where there's no failure it's: md5sum (GNU coreutils) 9.5
but as noted, that exact binary moved to 25.10 to replace /usr/bin/md5sum
does not improve matters there.
