During the PostX 0.4.2 a bug appeared. Originally, I wrote the text below from it:
“Important note. There seems to be a bug in Debian base(release building packages related). The bug appears when trying to start the installed system. The virtual terminal console number 2 gets stuck and only a black screen is showing when the login should appear. To overcome this issue press some of the following key combinations to open an alternative terminal….”
The actual error message is something like this: “Type “ONE_LEVEL” has 1 levels, but <RALT> has 2 symbols“.
The cause of this bug is not the Debian base but the Kernel. There seems to be some sort of bug in the 4.9.18 version, which causes the issues to appear. I have actually seen a variant of these issues before, which also manifested themselves via keyboard issues. I am now building new kernels and as soon as I can confirm that the keyboard issues are out I will release a 0.4.3 version of PostX Gnu/Linux containing fixes and all the recent software upgrades.
