Hi wondering if you had any thoughts on whether this as possible? I…e running the script from the CLI would always check for an updated script? And download it?
update-tailscale.sh
thanks 
Feel free to add the necessary cronjobs to your crontab.
Use the --force switch so it will skip all confirmations.
Thanks for the script, it worked with Mudi. However, every command with ‘tailscale’ results in “Segmentation fault” as response and I cannot set manual commands for subnet or exit node. Any ideas how to troubleshoot or fix it? ‘Tailscaled -version’ gives fine result, ‘tailscale version’ outputs segmentation fault.
I don’t own an Mudi so I can’t test it right now. Could be possible that the newest tailscale version does not work on Mudi.
Could be indeed, however, from Tailscale GUI I can enable it and subnets and seem to work fine so far, only command line fails. Is there a way to install earlier version of Tailscale with script or best to do manually? Thanks.
Manually is the only way, sorry.
What is “Tailscale”? For what it is used for?

The update was successful. Do you want to make the installation permanent?
This will make your tailscale installation persistent over firmware upgrades.
Please note that this is not officially supported by GL.iNet.
It could lead to issues, even if not likely. Just keep that in mind.
In worst case, you might need to remove the config from /etc/sysupgrade.conf

If I don’t compress the files I still get errors.

Yup, seems like the download fails. Will further investigate.

I updated the script to check if the download was successfully before continuing.
@Vincent123 please re-run the script.

No, it’s an error with your device / internet connection.

Guess the update file does not exist?
It does. Do you use VPN or something like that?
I have adblock on my main router that my ar750s is connected to and I do have vpn on my ar750s. I have disabled vpn on my ar750s and have tethered my phone connection to it to eliminate my main router and it is still the same, guess I can’t update it.
Can you please execute:
wget -O /tmp/tailscale.tar.gz "https://pkgs.tailscale.com/stable/tailscale_1.64.0_mips.tgz"
