Installed Manjaro 15.12 using the Thus installer and set a password for the install to be encrypted. I've been using this install for 1 week or so.

Yesterday: Updated various packages using Octopi and rebooted. At the "enter password for cryptManjaro" screen prior to Manjaro booting, the valid password no longer works (ie, it doesn't let me in, no message, just wipes the password box and invites me to submit another).

Re-installed and set an "easy" password, avoiding any characters that might be on a non-US keyboard. (e.g. "password1234".)

Rebooted without update.

At the password prompt, I entered "password1234".
It let me in.

After login, I updated every package in Octopi.

Rebooted.

"password1234" no longer works.

For clarity: I am talking here about the encryption password, not the account/root password.

Obviously, the encryption is to keep out potential adversaries. If this doesn't function well enough for me, the genuine user, then this function is useless as it locks me out of my own files/data. Unless this is fixed, I am thinking of shifting to OpenSuse, etc.

Any ideas? Anyone else experienced this bug? I have to say, I feel lucky this didn't happen to me after a long time of using Manjaro. Then I would have been very angry at having lost access to an install I invested a lot of time in.

Hello,

I experienced the same problem. Any solution already?
I am using my system since 10 month. This is very bad for me.

Thanks in advance.

I can report that the problem is known and solved.

What happened is that the Manjaro guys included the encryption option starting from kernel 4.5, and then backported it. However, it doesn't work with all previous kernel versions: seems like a bug got through.

So the detailed solution, including how to rescue your system, is here:

I was lucky in that I was messing around with installs, so I could do a fresh install, update the kernel, then reboot, then accept the latest updates and not be affected. But, as I say, the instructions on how to rescue your system if you've already fallen victim to the bug, see the link above. It most likely will need a boot from a Live CD.

One more thing:

I reinstalled manjaro from the (very) recent 16.06 experimental .iso. It works fine, encryption, updates, etc. It also has the advantage of not coming with a lot of software, so you can install what you want and have a faster boot time.

The Cinnamon 16.06 works great too.

Both run 4.4.3 kernel.
