Opkg update Failed ; wget returned 3 ; but wget works if manually typed!

matlag · January 28, 2023, 12:44am

Hi all,

I would think it's a filesystem issue rather than a network issue, but well:

I set up my router as a dumb AP. No issue so far.

But when doing opkg update, drama starts:

opkg_download: Failed to download https://downloads.openwrt.org/releases/22.03.2/targets/mvebu/cortexa9/packag
es/Packages.gz, wget returned 3

Code 3 is "File I/O"

But if as root, I do:

wget https://downloads.openwrt.org/releases/22.03.2/targets/mvebu/cortexa9/packages/Packages.gz

Then it works, I have now the file on my system!

I have an external hard-drive, and use it for extra-system space (it hosts an Ad Guard Home). I assume opkg attempts to download in a space where it can't (??). What would that be, and how do I move that to the external driver?

Thanks very much!

psherman · January 28, 2023, 3:10am

your tmpfs is completely full and you have swap that is using quite a bit of memory, too. What is running on this device?

mk24 · January 28, 2023, 3:18am

Yes the zero free on /tmp is the problem. You've probably storing large log files on /tmp.

The files on /tmp also tie up half of the RAM, making swapping necessary.

matlag · January 28, 2023, 4:11am

Aaaaah!
I run AdGuardHome, and indeed, that's what's filling /tmp!
I think I need to move things around...

Thanks!

psherman · January 28, 2023, 4:13am

Yeah, that will do it. Moving files out of tmp (or changing the maximum size of logs and such that are using that space) should fix it.

If your problem is solved, please consider marking this topic as [Solved]. See How to mark a topic as [Solved] for a short how-to.

matlag · January 28, 2023, 10:55pm

My /var was a link to /tmp, itself in the RAM.

cp the whole thing to a /var1, deleted /var and moved /var1 to /var in a single command line, reboot, and now all is fine!

Thanks very much!

psherman · January 28, 2023, 11:20pm

This is normal.

The real question is why your var (tmp) was filling up. What was being stored there?

matlag · January 29, 2023, 2:59am

It was the AdguardHome logs.
