Po více než 7 měsících vývoje od vydání verze 6.8 byla vydána nová verze 6.9 svobodného open source redakčního systému WordPress. Kódové jméno Gene bylo vybráno na počest amerického jazzového klavíristy Gene Harrise (Ray Brown Trio - Summertime).
Na čem pracují vývojáři webového prohlížeče Ladybird (GitHub)? Byl publikován přehled vývoje za listopad (YouTube).
Google Chrome 143 byl prohlášen za stabilní. Nejnovější stabilní verze 143.0.7499.40 přináší řadu novinek z hlediska uživatelů i vývojářů. Podrobný přehled v poznámkách k vydání. Opraveno bylo 13 bezpečnostních chyb.
Společnost Valve aktualizovala přehled o hardwarovém a softwarovém vybavení uživatelů služby Steam. Podíl uživatelů Linuxu dosáhl 3,2 %. Nejčastěji používané linuxové distribuce jsou Arch Linux, Linux Mint a Ubuntu. Při výběru jenom Linuxu vede SteamOS Holo s 26,42 %. Procesor AMD používá 66,72 % hráčů na Linuxu.
Canonical oznámil (YouTube), že nově nabízí svou podporu Ubuntu Pro také pro instance Ubuntu na WSL (Windows Subsystem for Linux).
Samsung představil svůj nejnovější chytrý telefon Galaxy Z TriFold (YouTube). Skládačka se nerozkládá jednou, ale hned dvakrát, a nabízí displej s úhlopříčkou 10 palců. V České republice nebude tento model dostupný.
Armbian, tj. linuxová distribuce založená na Debianu a Ubuntu optimalizovaná pro jednodeskové počítače na platformě ARM a RISC-V, ke stažení ale také pro Intel a AMD, byl vydán ve verzi 25.11.1. Přehled novinek v Changelogu.
Byla vydána nová verze 15.0 svobodného unixového operačního systému FreeBSD. Podrobný přehled novinek v poznámkách k vydání.
UBports, nadace a komunita kolem Ubuntu pro telefony a tablety Ubuntu Touch, vydala Ubuntu Touch 24.04 1.1 a 20.04 OTA-11. Vedle oprav chyb a drobných vylepšení je řešen také středně závažný bezpečnostní problém.

Restart jsem nezkoušel protože je poškozen login, mám obavy že server nenaběhne a jeho provoz je kritický.
Přihlašuji se pomocí ssh.
V logu jsem nic nenašel jen chyby disku, ale myslím, že ty souvisí s poškozenými soubory ne se samotným HW.

Prosím o jakýkoliv nápad na řešení jak se zbavit chybných souborů
Děkuji za jakoukoliv přínosnou pomoc.
Ja si naopak myslim, ze mate HW problem, ktery s nejvetsi pravdepodobnosti zpusobuje problemy s filesystemem. Rozhodne bych se podival na podrobnosti ve SMARTu disku.
Tak si mount a dalsi utility nakopirujte z jineho stroje treba do /root/ a spoustejte je tam.
Soubory nejspis nemuzete smazat proto, ze se korenovy filesystem automaticky premountoval jako read-only po zaznamenani chyb.
Děkuji,
máte pravdu, opravdu je vadný druhý disk v raidu sdb2

Takže to bychom měli proč, nyní jsem tedy "rozbil" raid a zkontroloval jestli opravdu :)

vytvořil zálohy pomocí nakopírování mount do root jak říkáte, děkuji,
disky, tedy teď již jen sda2, je RW, do adresáře /bin můžu zapisovat/mazat, ale stále mě trápí ty nesmyslné práva, délky u výše zmiňovaných souborů a stále nevím jak se jich zbavit. Smazat stále nejdou, znovu zkouším mazat podle i-node. Potřeboval bych se jich zbavit před opravou raid, abych nekopíroval vadné soubory.
