A few days ago, my ubuntu console started printing '^A' whenever I hit 'CTRL+A', instead of moving the cursor to the start of the line as it did before. The same problem happens for 'CTRL+E', while the 'CTRL+Arrow' shortcuts behave as they should. However, if I log in to a remote machine via ssh, everything works fine. Unfortunately, I do not remember anything in particular which could have triggered this behaviour (I have not changed shortcuts, nor modified my '.bashrc' file, nor updated the system).
some useful information:
I am not using nor screen nor tmux or other terminal multiplexers;

Thank you in advance if you give me some ideas about what could I try.
