NixOS - error: getting attributes of path... : No such file or directorych file or directory

00-error.md

I started to consistently use NixOS and then plasma5+i3-xsession. In the last few weeks it froze three times, forcing to hard reboot each time.

Not sure it'd happen only with plasma5+i3-xsession, it just never happened with kde/plasma and with stand-alone i3 session.

Note: I added the unstable channel for a few programs, but the freezing already happened before it.

I managed to fix(?) several error: getting attributes of path:

$ sudo nixos-rebuild dry-activate

// seems okay, but...

Probably this was not the right way and something is broken now. When I switch the configuration:

• it probably fails completely (as I find only one new generation in boot menu, not several)

• it spits me to a tty (dry-activate is the only thing that does not do it)

• if I reboot with the last generation, I only get a tty

• I can "normally" boot in a previous generation

• and I am stuck in this broken loop

Seems that a lot of systemd stuff was broken(?).

After 2323432 hours of this dance:

and it stopped.

Let's check with a

$ sudo nixos-rebuild dry-activate
building Nix...
building the system configuration...

Uhm 🤔 ... Let's try a

$ sudo nixos-rebuild test

For posterity:

if successful I will update this gist ASAP. Otherwise, let's hope that will not break everything and definitely 😌

It is alive... Now:

$ sudo nixos-rebuild switch --upgrade --show-trace 

It apparently work, but (seems that) does not produce a new generation 🤔

Rebooted, so far so good. Apparently I am in the last generation and it works.

TODO:

• update configuration and rebuild again
