So, I have the RTL8723BE problem. I tried to fix it. I downloaded rtlwifi and installed it (success), but at some point, I lost my wifi connection. Then, i got the "modprobe: ERROR: could not insert 'rtl8723be': Required key not available" so i followed this instructions. It all went well until i got to this part:

sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n rtl8723be)

which gave me this error

modinfo: ERROR: missing module or filename.
Usage: scripts/sign-file [-dp] <hash algo> <key> <x509> <module> [<dest>]
scripts/sign-file -s <hash algo> <x509> <module> [<dest>]

Because of that error I did not continue, because I imagine it's useless. What can I do?

  • You shouldn't need rtlwifi-new if you have kernel 4.4 or newer – Jeremy31 Jun 28 '18 at 10:35
  • @Jeremy31 I just checked and I have kernel 4.13. Should I just update it? (And would any ubuntu "tutorial" work for that?) – Julia Sepúlveda Jun 29 '18 at 16:48
  • Lol i've just realised the first number is not what counts the most hahaha. So, now that I know I have a newer kernel than 4.4, what kind of solution should I try? – Julia Sepúlveda Jun 29 '18 at 17:24
  • Ok so great, now it works, I don't know why, but it works. Thanks I guess? – Julia Sepúlveda Jun 29 '18 at 17:31
