eventually this worked:
opkg remove tailscale --force-depends
opkg install tailscale
sudo ./update-tailscale.sh

Great to hear!
sudo isn't necessary on OpenWrt, btw. Everything runs as root by default.

right, of course..... 
Thanks a lot for your work! I can confirm that this script not only working on my GL-MT3000 but also on my three Xiaomi AX3000T OpenWRT 23.05.2 routers. It also frees up some space greatly since non-tiny Tailscale.ipk is about 10mb but your script is updating it to tiny version of Tailscale.

Hi Admon,
I checked your script on GL-E750 V2 (Mudi), it downloads an install version which crashes. Do you know any version of updated Tailscale which can run on this device (without replacing the entire firmware...)
@Dorin @MucFlyer
I don't own a Mudi and can't test - but I assumed it might use "mipsel" instead of "mips".
Could you please re-try the newest version of the script?
I wrote a post, mentioning your update script as well as the official binaries from Tailscale with some simple explanation.

Mudi is unfortunately not supported yet, I am sorry 
Just wanted to say thank you to @admon for writing and maintaining the script!

Hi @admon do you have script like this on zerotier? Gl-zerotier version 1.10 latest version is 1.14.
Unfortunately not, I am sorry.

No worries, I am happy to setup SSH/GUI access if you would like to remote in and review what it might take to make it work.
I know the issue, I am just not able to build a working version without having hands on.
Maybe I will buy a MudiV2 in future and try it.
Hi Admon!
Good job, script worked well on my Brume2.
However, when I tried to update Tailscale on Mango router (GL-MT300N-V2) it didn't work.
Most probably because Mango has mipsle (MIPS 32-bit little-endian) architecture.
I've checked Router original files (v1.32.3-1) with Cygwin:
I managed to update it manually using these binaries:
- mipsle: tailscale_1.76.1_mipsle.tgz
Thanks for your information, I added support for the Mango as well

Hi, thanks for your effort with this.
Is ts.net lan an expected, non-problematic value for this field after running this script? I didn't realize more than one suffix could live in that field..?
My script does not modify this so I can't tell. Must be something you added by yourself.
I'm almost certain I didn't put ts.net in myself, but I can't prove it because my memory is Swiss cheese. I had to factory reset one of my routers and will be installing Tailscale and updating via your script, I'll let you know if it shows up again.
Edit: It's also set like that on my Beryl AX - I may be only 92% sure I didn't set that myself on one device, but I'm like 99.8% sure I didn't set it myself on two of them.
Am I correct in thinking that field can't normally contain a space-separated list of values?
