[vpsFree.cz: community-list] Arch Linux a nový problém s dockerem

[Ladislav Laska]

Ahoj,

píšu takhle večer a jsem unavený, tak se nezlobte zda jsem přehlédl
nějkou blbost, ale při upgradu systému (Arch Linux) na svojí VPS jsem
narazil na problém, že mi přestal chodit docker. Oprava je na konci
emailu, tak třeba to někomu ušetří trochu práce a stresu.

Update prošel podle následujícího logu:

Potom začal ale docker při spouštění triviálních věcí (docker run hello-world) nechávat tyto věci na terminálu i v journálu:

Apr 15 22:55:26 mouflon dockerd[2006]: time="2021-04-15T22:55:26.728977443+02:00" level=error msg="Handler for POST /v1.41/containers/fc72a2108933f3f8fd557151a9b46c79aec1fa3acb71f0e30af4ca9e40b7b29f/start returned error: OCI runtime create failed: container_linux.go:367: starting container process caused: process_linux.go:495: container init caused: process_linux.go:458: setting cgroup config for procHooks process caused: can't load program: operation not permitted: unknown"

... Říkal jsem si, že to otestuju na staging a ověřím, co je přesně
problém, ale na stagingu (čerstvě vytvořená vps 19335) mi nefunguje
šablona Arch Linuxu:

# pacman -Syy docker

[...]
error: libxcrypt: signature from "Christian Hesse <eworm at archlinux.org>" is unknown trust
:: File /var/cache/pacman/pkg/libxcrypt-4.4.19-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).



... Nakonec jsem downgradoval docker na 1:20.10.5-1, to ale nestačilo.
Downgradoval jsem tedy také systemd* na 247.4-2 (systemd, systemd-libs,
systemd-sysvcompat), to taky nepomohlo, ale po restartu vps už to celé
zabralo.

V tuhle hodinu už to debugovat nechci, zítra se podívám jestli to nějak
umím doklepnout v té staging vpsce.

Kdyby náhodou někdo věděl co se děje, rád si ušetřím práci.

Zdar a dobrou noc,
s pozdravem Ladislav Láska
