I ve a problem while updating my system. I figured out that there is a problem by updating grub during the "sudo apt upgrade".
Removing linux-image-5.4.0-42-generic (5.4.0-42.46) ... /etc/kernel/postrm.d/initramfs-tools: update-initramfs: Deleting /boot/initrd.img-5.4.0-42-generic /etc/kernel/postrm.d/zz-update-grub: Sourcing file `/etc/default/grub' /usr/sbin/grub-mkconfig: 11: /etc/default/grub: : Permission denied run-parts: /etc/kernel/postrm.d/zz-update-grub exited with return code 127 dpkg: error processing package linux-image-5.4.0-42-generic (--remove): installed linux-image-5.4.0-42-generic package post-removal script subprocess returned error exit status 1 dpkg: too many errors, stopping Errors were encountered while processing: linux-image-5.4.0-42-generic Processing was halted because there were too many errors. E: Sub-process /usr/bin/dpkg returned an error code (1)
than I tried also "sudo update-grub" and got this
Sourcing file `/etc/default/grub' /usr/sbin/grub-mkconfig: 11: /etc/default/grub: : Permission denied
The grub file (/etc/default/grub) itself looks the following:
# If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX= "" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"
"ls -ldh /etc/default/grub"

Does anyone have an idea?
