another crash (Failed to read disk "/dev/nvme0n1p3" with lsblk)

[treeshateorcs]

I tried to install Arch after installing Debian (which has a little different disk layout (/dev/nvme0n1p{1,2,3})) and this happened on the first run of archinstall. After I ran it the second time it worked successfully

The exact same thing happened to me. Attaching the log file: here
As the OP stated, when re-running the script it works.

[svartkanin]

Thanks for reporting this, I managed to reproduce it and a fix is up #2498

[DeN-AlB]

Tried to install Arch Linux with archinstall and got the same error some hours ago.

Now tried again after the fix was applied and it worked! Thanks a lot! 👍

Hi! The same just happened to me. Another thing that I noticed is that the first time around, there was a menu for Disk Encryption, but when I re-ran the script, that menu was gone and, thus far, everything seems to be working just fine.

[svartkanin]

It's fixed in master but not released yet

[ADPenrose]

Thanks for the heads up!
