[SOLVED] Sudden permission issues with wget

I use a script to update various local files with the newer versions available online. Suddenly, after many months of use, today it stopped working.

Commands like:
sudo wget ftp://ftp.internic.net/domain/named.cache -O /usr/local/share/named
or
sudo wget https://svn.nmap.org/nmap/nmap-os-db -O /usr/share/nmap/nmap-os-db
fail with a "read-only file system" error, but if I create or edit the same outfile file with "sudo nano" it works.

Same thing with other folders in /usr or /etc. I fsck'ed the partition and there are no errors, nor it's mounted read-only (I can create or delete any file I want).

I noticed those root-owned folders have rwxr-xr-x permission so maybe that's the problem, but I installed Arch months ago and didn't touch permissions, so I don't know if either a recent update (via pacman) changed them, or if it's something else. Any idea?

If you're sure it was today that it stopped working; then have a look at what's different, have you updated anything, or made changes to something? Check the pacman log to jog your memory.

Re: [SOLVED] Sudden permission issues with wget

mount
type wget
stat `which wget`

and you may want to strace the call (don't sudo strace, but run it as root. "sudo strace foo" won't work)

Re: [SOLVED] Sudden permission issues with wget

...why are you running wget as root anyway.

Re: [SOLVED] Sudden permission issues with wget

Because he wants it to directly write into a root owned path.
Probably not the smartest of all approaches, but it shouldn't fail this way either.

Re: [SOLVED] Sudden permission issues with wget

mount
type wget
stat `which wget`

$ stat `which wget`
File: /usr/local/bin/wget -> /usr/bin/firejail

Ah, that's the culprit! I recently installed firejail and it seems it also has a profile for wget.

Solved, thanks for your help!

You're right, now I changed it to wget to tmp and only use sudo to move the file to the destination directory.
