I am wondering if I can legally install and use the Ubuntu Restricted Codecs metapackage in the United States? How am I allowed to access these proprietary codecs for free?
I recently switched my Lenovo thinkpad X1 yoga 4th gen to Ubuntu 24. I use this computer for work and have been unable to print to our main office printer since making the switch. We have two printers at the office and I am able to print to the Canon MF 1643i II in our med office, but not the Canon IR AdvanceDX C3835i. I can see both printers in my printers list in settings, but I am only able to print from the Canon MF.
I have installed cups and checked that it is running which it is. I have pulled up the cups gui at localhost:361 and attempted to login using my name and password for my machine, but it did not work. Now when I try, the admin page does not ask me for credentials and simply says unauthorized. I am hoping for help in getting back access to cups admin page or a workaround to add the printer without the need for the gui. I am most definitely a linux newb in many ways, so please know that I will need some basic hand holding type of guidance. Thank you all in advance!
Suppose I have a file selected in Files. How can I copy it's full file path to the clipboard? hitting <CTRL>+L followed by <CTRL>+C (or <CTRL>+X) just copies the path of the parent directory to the clipboard. How to get the full path copied to clipboard?
I am not looking for drag-and-drop functionality (e.g., I already know I can drag the file to, say the terminal app, to paste it's path there).
I would like to run the find command and get some of the files/directories in the desktop directory using regex option of the command with the symbol caret ^
As you know the caret ^ matches the beginning of a line, and I would like to get all the files/directories starting with the letter t; I used the following command find . -regex "^./t", but as it turned out, it will only match the file/folder whose name is a simple t!
I know that the regex will match the whole path and not only the file name. But why all of these do not match since they start with ./t.
./tcpdump.txt
./t.txt
./test.sh
./trade.txt
./torbrowser.desktop
./token.txt
PS: This regex worked for me, ^./t.*, but still unable to understand the behavior of caret in the original command
For some reason GRUB will not update the list of available kernels after a routine update

I completely purged version 45 and reinstalled it. I cant see any errors and neither can apt.
When I reboot I will end up in emergency mode and I have to manually move back to the 44 version of the kernel via
update-initramfs -u -k 6.8.0-44-generic
Then the system boots as expected - but on the old kernel.
What is up with grub?
