I am new to ubuntu and recently installed ubuntu 20.04 on my system.
At the time of installation, I was getting this error:
PCIe bus error severity=corrected type=physical layer (receiver id)
for encounter this problem I did:
Add pci=noaer at the end of GRUB_CMDLINE_LINUX_DEFAULT in the grub file.
Then my kern.log file was getting pretty big, as big that it was consuming the whole of my root folder. For this, I installed ubuntu using an internet connection. and this problem was also solved.
Now on running sudo apt update
I am getting this error:
E: Could not get lock /var/lib/apt/lists/lock. It is held by process 1165 (packagekitd)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/
I couldn't even remove this lock file; as my whole system will crash out,
May you please help me to encounter this error, I will be very much thankful to the whole of the community.
