Fedora 31 upgrade log

Upgrading Linux is always a challenging task. It will cause my heart beating fast, my head was spinning, and I was sweating. This round I was upgrading Fedora 30 to 31, there are few errors pops up during the upgrade. The first challenge is when the package gpgme(x86-64) required by python2-gpg couldn't be found.

$ sudo dnf system-upgrade download --releasever=31

...
...

Error: 
 Problem: package python2-gpg-1.13.1-7.fc30.x86_64 requires gpgme(x86-64) = 1.13.1-7.fc30, but none of the providers can be installed
  - gpgme-1.13.1-7.fc30.x86_64 does not belong to a distupgrade repository
  - problem with installed package python2-gpg-1.13.1-7.fc30.x86_64
(try to add '--skip-broken' to skip uninstallable packages)

I found a link mention that Python 2 has end of life, and thus the dependencies required by Python 2 waren't there anymore. Googling around couldn't find a solution on this, but I found a similar problem where the workaround is to remove the package.

$ sudo dnf remove python2-gpg-1.13.1-7.fc30.x86_64

A bunch of Python 2 related dependencies was removed. Now come to the next challenge, it shows that Cannot enable multiple streams for module 'gimp'. What the hell exactly of this? 

$ sudo dnf system-upgrade download --releasever=31

...
...

terminate called after throwing an instance of 'libdnf::ModulePackageContainer::EnableMultipleStreamsException'
  what():  Cannot enable multiple streams for module 'gimp'
Aborted

There is exactly the same error has been reported to Redhat Bugzilla, but that one is caused by VirtualBox. Then I found this guide which is quite straight forward to use.

$ sudo dnf module disable gimp

Now only I can proceed to upgrade the system. The next biggest challenge would be the driver. This always failed me. When I compile the driver with DKMS, it failed due to the compilation error shown in the make.log:

implicit declaration of function ‘ioremap_nocache’; did you mean ‘ioremap_cache’?

As I check in the NVIDIA driver source code, there are plenty of the function named ioremap_nocache. This is so unwise if I change it manually, throughout my professional career, programming does not work in that way. After a long search on the Internet, there is a patch for NVIDIA 390.132 driver. Use that patch driver instead of the original download from the NVIDIA website. Once done, verify with the following command and I got the driver installed successfully.
