update gazebo

gazebo -v 
sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install gazebo[distro]

• if install ros with root:

  chown -R xihan /home/xihan/catkin_ws

install upstream linux kernel from source

step1. download kernel files

download from https://www.kernel.org/pub/linux/kernel, for example

curl -SLO https://www.kernel.org/pub/linux/kernel/v5.x/linux-5.19.1.tar.xz
curl -SLO https://www.kernel.org/pub/linux/kernel/v5.x/linux-5.19.1.tar.sign

decompress:

xz -d *.xz

step2. verify file integrity

gpg2 --verify linux-*.tar.sign
gpg2 --verify patch-*.patch.sign

in case of missing public key:

gpg2  --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys $(missed public key)

step3 customize kernel configuration (important step!!!)

tar xf linux-*.tar
cd linux-*/
patch -p1 < ../patch-*.patch
cp -v /boot/config-$(uname -r) .config
make olddefconfig
make menuconfig

Navigate to Cryptographic API > Certificates for signature checking > Provide system-wide ring of trusted keys > Additional X.509 keys for default system keyring Remove “debian/canonical-certs.pem” and “debian/canonical-revoked-certs.pem”

step4. compile and installation

make -j$(nproc) deb-pkg
sudo dpkg -i ../linux-headers-*.deb ../linux-image-*.deb

intel iwlwifi driver issue

git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install

fix Nvidia driver modules
