Ok, so I screw up my last actualization of Ubuntu - I was not paying attention and during this I encountered a lot of problems, in the end my laptop stopped working. I tried to reanimate it, but to no avail - it seems that my entire system is not responding.
Therefore, I tried to repair this by installing new Ubuntu - however, during installation (no matter my choices, be it install completetly new or recover old system) i keep getting „Errno 5 - input/output error”. I changed my USB stick, i used different entrances, I checked my ISO file. It seems the problem may be connected with problems on my filesystems.
I tried to check my filesystems with fsck commands, but it keeps saying my that i can’t do that and All answers on the internet tell me, that i need to reboot it to kill all my processes to be able to umount it. However, if i do reboot it, i can’t go back and have to boot it from the start. Is there any other way to kill all programs or to remove Errno5 problem?
fsckdo not check disks for errors, they perform file-system checks which are logical checks of the metadata of the file-system; your disk can be 99% dead but if the part of the disk that contains that metadata still worksfsckwill work. What device did you get the IO error (ie. hardware error), as that part of the detail is necessary (ie. read the context & full message(s) including those just prior in logs). As we don't know what you were doing; we only know you have hardware problems (being limited to only what you provide which included no context) – guiverc Mar 07 '23 at 21:48
