thanks secure boot was enabled so fixed that issue

They link to an older page:

You need to clear the secure boot keys in bios after disabling secure boot

So disabling it is not enough. How many people can figure that out?

error: bad shim signature

We also keep seeing reports of machines tinkering with the digital 'jumper', turning back on 'secure' (not!) boot in defiance of what users configure their own PCs to do.

minisforum v3 se randomly enables secure boot and making problems to run linux before disable again

Hello

After installing arch linux on minisforum v3 se, every one or 2 days i dont know why, but this tablet enable secure boot if is disabled..

If i want to enable secure boot then i should to do that by myself because i took tablet to work without magnetic keyboard for vacations for one week and this tablet enabled secure boot and i was not able to run linux and any other os because i can use bios setings with touchpad and keyboard is needed.. its so annoing.. i even consider to install windows again because i wasted almost 4 days till i was back at home after holidays..

that was never happen before with any laptop which i have before.. acer, asus etc but i really like linux and i dont want to change os, any ideas or uggestions how to fix that annoing problem?

This is mentally exhausting to Linux users ("i even consider to install windows again because i wasted almost 4 days till i was back at home after holidays...").

Also a few hours ago we saw similar reports. This is becoming a pain in the back end to Linux users, who don't want this back door.
