panic with pkg

[ptr]

I am running V11.0 without problems.
pkg install xfburn
does update the database first and offered an update of pkg: I answered yes.
after that I did again pkg install xfburn.
it showed the packages to install, answered yes again, the download started
but stopped after 33% of the first file and no more move possible. Therefore
I pushed the powerbutton, the system shut down.
Reboot and pkg install xfburn and immediately the prompt came up.
fsck -y showed that the man8 directory was damaged and could not be repaired because
the system is only readable.
man pkg gave this message:

root has access to the internet and user can do all things.
pkg does not do anything even when I try to downgrade from 1.10 to 1.9.4_1.

Any idea what to do and how?

First 2 things. You're more or less hijacking a thread. Your problem has not much to do with the problem of the OP; those previous problems were fully pkg related whereas yours is more file system related.

And well... There's really no need to post twice.

answered yes again, the download started
but stopped after 33% of the first file and no more move possible. Therefore
I pushed the powerbutton, the system shut down.

What is your definition of "shut down"?

Did it shut down cleanly as if you used # shutdown now -p or did it just turn off? Because from what you're describing I'd say it did not shutdown but it shut off.

Reboot and pkg install xfburn and immediately the prompt came up. fsck -y showed that the man8 directory was damaged and could not be repaired because
the system is only readable.

No, file systems don't work that way. It's not a directory which got damaged but an entry on your filesystem. Something which the boot process would have caught because of an unclean shutdown.

Another theory is that your harddisk is going bad and you're now seeing the results of that. But I'm more inclined to think that you didn't perform a clean shutdown.

Any idea what to do and how?

Start in single user mode, and run fsck on the affected filesystem. Optionally you might also want to check the health of your harddisk.

I am back to the forum after some health issues.

1. You are right ShelLuser: as a potter now retired I never had the chance of intellectual training for step-by-step-learning of computing-programming-hacking like some (many?, most?) of you ladies and gentlemen here in the forum. But since I was confronted with using a computer 17 years ago I managed my little tasks somehow on win98 first and a quick change to Linux. 7 months ago I changed to FreeBSD with great pleasure: well structured, good documentation, patience in the forum. I continue learning.

2. You are right: it is a problem of harddisk. I always had old hardware of people who did not like their laptops anymore. My actual one is 11 years old, I use it 7 years. I cannot install Ubuntu and derivates because they are complaining about imminent disk-failure. In the meantime I made 2 fresh installs on the same partition and had the same problems after a short while. The laptop has the bootoption "USB HDD", so I made a FreeBSD install on a 32GB sdcard with a cardreader: it runs without problems.
