I didn’t experience any weirdness today actually, paru pushed the important message of what to pay attention and what to do in order to do this one time transitional update.
In fact, people facing issues still on Arch and on EndeavourOS and only Cachy could withstand this, thanks to ptr1337’s sane thinking. He downgraded the firmwares version back to 0508 on cachy repo, until they fix the stuffs on arch’s end. Make sure to do another paru and let it downgrade firmwares back to 0508 and those issues should vanish then.
