I got the following problem on 18.04:

  • GCC was updated from GCC 7.3 to GCC 7.4
  • A new kernel was installed (compiled with 7.3)

Now the NVIDIA driver will not install as it requires that the installed version was also used to compile the kernel.

I tried the IGNORE_CC_MISMATCH without success. What is the preferred way of solving the problem:

  • Recompile the kernel package with the current gcc
  • Downgrade GCC to 7.3

I guess one should file a bug to canonical (title: Always deploy kernels compiled with current version of GCC).

  • You should install the version in the repository. You can use Additional Drivers for that. Do not install the binary from Nvidia. – GabrielaGarcia Apr 30 at 10:30
  • @GabrielaGarcia Sometimes, that package is broken too – user877329 Apr 30 at 10:38
  • It's possible but very unlikely, rarely. – GabrielaGarcia Apr 30 at 10:39
  • You need to download the latest Nvidia driver that is compatible with your Kernel version you can download it from nvidia website or use the proprietary drivers from Ubuntu. – JoKeR Apr 30 at 10:57

    use sudo sh ./NVIDIA-Linux-x86_64-*.run --no-cc-version-check I believe NVIDIA-Linux-x86_64-*.run is unsetting IGNORE_CC_MISMATCH unless you use the --no-cc-version-check flag. See askubuntu.com/a/1143434/144906 – Wandering Logic May 15 at 19:58
