[SOLVED] Pacman Segfault after upgrade runs out of space

I might have bricked something. Pacman has run out of disk space while upgrading.
It aborted transaction on curl.

Now it does not even start.

Segmentation fault (core dumped)

strace pacman

Re: [SOLVED] Pacman Segfault after upgrade runs out of space

See if you have enough disk space left. What's the output of

df -h

Re: [SOLVED] Pacman Segfault after upgrade runs out of space

Right sorry, free up some space was the first thing I did.

/dev/sda4        28G   27G  564M  98% /

Re: [SOLVED] Pacman Segfault after upgrade runs out of space

Which filesystem are you using? If it's one from the ext family, then by default 5% of the space is reserved space. Perhaps you need to free up some more space.

Re: [SOLVED] Pacman Segfault after upgrade runs out of space

Fixed it by the nuclear option.

I've run live usb disk and force reinstalled all packages using pacman. Nothing else worked. Even not using --force did not work.
