Operating system is in read-only mode

[Качинский]

Hi all! When I try to use the pacman command, a message pops up stating that the operating system is in read-only mode.
how can I fix this?

To fix this, run "sudo steamos-readonly disable" in Konsole (a user password must be set first, can be done by running the "passwd" command), but keep in mind that any changes to the file system will be wiped in the next SteamOS update. You can also add specific directories to persist in the next SteamOS update in the "atomic-update-keep.conf" file located in /usr/lib/rauc. See "/etc/atomic-update.conf.d/example-additional-keeplist.conf" for examples.

Edit: You must enter Desktop Mode before doing this, can be done by holding the power button and selecting "Switch to Desktop".
