Hi everyone,
I have been using a Librem 13v4 with Librem Key for around 3 years. My current operating system is Qubes OS 4.0.
Now when booting, I received the following error message
gpg: key ... was created ... days in the future (time warp or clock problem)
gpg: Can't check signature: Bad public key
Failed default boot
I managed to fix the issue (incorrect BIOS system time of 1.1.1970) by forcing unsafe boot, setting the system time manually ( date -s '2014-12-25 12:34:56'
) and setting the BIOS time to the system time (hwclock --systohc
). However, I would not like this to be the regular fix as it means that tampering cannot be detected.
To properly fix the issue, I was wondering if the problem is that the Bios battery is getting weak. I have used the laptop for around 3 years around 3 hours per week and almost always plugged in. Does anyone have similar experiences? Is there any documentation how to replace the BIOS battery for this laptop?
