you need to be running 21.02 POST rc1 ( netifd post '2021-05-20' )

I installed a package from here:

https://downloads.openwrt.org/releases/21.02.0/targets/x86/64/

Is that not the first stable 21.02 release?

can you explain in more detail the exact OS you installed and exact stuff you installed into it?

[root@dca632 /usbstick 46°] curl -sSL https://downloads.openwrt.org/releases/21.02.0/targets/x86/64/openwrt-21.02.0-x86-64.manifest | grep netifd
netifd - 2021-07-26-440eb064-1

suspect you installed a different image, or similar unknown custom things, as above, 21.02.0 netifd is 2021-07.

Sure. I installed this OS package over 19.07.8 via the web UI, with "keep settings" checked:

https://downloads.openwrt.org/releases/21.02.0/targets/x86/64/openwrt-21.02.0-x86-64-generic-ext4-combined.img.gz

I then installed the following packages via opkg install <package name>:

block-mount
ca-bundle
ca-certificates
conntrack
coreutils-date
coreutils-dd
coreutils-timeout
diffutils
dnsmasq-full

probably a stale extroot then?

I don't use extroot.

I will stop guessing then... but only you know why that is reporting an old version (what you have done to your system)

This is interesting. When I run opkg update it's updating from the 19.07 repos...

Any ideas why it might be doing that?

yeah, I do

Well, this gets even more interesting. It looks like it in fact did not upgrade at all.

Hmm. It just hangs if I try to remove gzip:

Removing package gzip from root...

For what it's worth, I see a zcat process running when this hung opkg command is running

13982 13973 root S 1072 0% 0% /bin/zcat

With opkg debug output on I see it's hanging while running this script:

pkg_run_script: Running script //usr/lib/opkg/info/gzip.postrm

Which looks like this:

#!/bin/sh
for app in gunzip gzip zcat; do
  ln -sf busybox ${IPKG_INSTROOT}/bin/$app
  ${IPKG_INSTROOT}/bin/$app 2>&1 | grep 'applet not found' > /dev/null 2>&1 && rm ${IPKG_INSTROOT}/bin/$app
done
exit 0

It looks like it's changed the symlinks in /bin though, so it might have done enough for the sysupgrade to work?

lrwxrwxrwx    1 root     root             7 Sep 15 10:56 /bin/gzip -> busybox
lrwxrwxrwx    1 root     root             7 Sep 15 10:56 /bin/zcat -> busybox
lrwxrwxrwx    1 root     root             7 Sep 15 10:56 /bin/gunzip -> busybox

Boom, that worked. I'm now upgraded to 21.02, and when I navigated to the Network -> Interfaces page in LuCI it automatically updated the config to the new syntax.

Thanks very much for your help. I think I would have really struggled to find that sysupgrade/gzip issue!
