"E: You don't have enough free space in /var/cache/apt/archives/" on ER-X

I am trying to install Tailscale, but I don't think my router has enough space. I have tried apt-get autoclean and apt-get clean, but I still don't have enough. Here is the output of df- h:

I was wondering if anyone encountered the same issue and how they fixed it.

@slipdip123 I've converted this to a discussion as an issue isn't really the right place. Maybe people are more likely to respond here.

Sorry about that! Haven’t used GitHub in a while

@slipdip123 Hi! Did you delete old system images?

As the following manual mentions, how about deleting old ones with delete system image command?

This worked! Thank you. Unfortunately it isn't letting me mark your answer as correct

Remember to uninstall tailscale when upgrading to a new firmware or the process will fail due to a lack of free space to create the backup image of your current firmware.
