我同意其他人在这里提出的同样的问题。在 ubuntu 22.04.2 上。这一切都发生在“apt-get update”之前：
root@host3:~# apt-get upgrade
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
linux-image-virtual
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
root@host3:~#
其次是：
root@host3:~# apt-get install linux-image-virtual
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
linux-image-5.15.0-76-generic : Depends: linux-modules-5.15.0-76-generic but it is not installable
E: Unable to correct problems, you have held broken packages.
root@host3:~#
其次是：
root@host3:~# apt-get install linux-modules-5.15.0-76-generic
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package linux-modules-5.15.0-76-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'linux-modules-5.15.0-76-generic' has no installation candidate
