[00:22] <auto25242[m]> System ask for update , after update installed my wired ethernet connection stop working. Is any way to fix it or uninstal last update? Thanks.
[00:24] <tomreyn> auto25242[m]: see /var/log/apt/terminal.log to understand which updates were installed.
[00:25] <tomreyn> about your ethernet connection: which chipset do you have, which driver is being used?
[00:25] <tomreyn> lspci -knn | grep -EA3 '(Network|Ethernet) controller' | nc termbin.com 9999 
[00:25] <tomreyn> ^ this will only work if you have internet access by some other means
[00:25] <tomreyn> if you don't use this:
[00:25] <tomreyn> lspci -knn | grep -EA3 '(Network|Ethernet) controller'
[00:27] <tomreyn> then, on the line where it says "Ethernet controller", provide the "[1234:abcd] (rev nn)" at the end of the line, as well as the values of "Kernel driver in use" and "Kernel modules"
[00:30] <auto25242[m]> Thank you tomreyn, but this is not for me, it is too complicated. 
[00:31] <tomreyn> it doesn't really require technical understanding other than being able to open a terminal window and typing some stuff
[00:32] <tomreyn> this command would provide the answers to the questions i asked
