The boot partition is just under 500M (457M according to df -h)

When installing the third kernel, update-initramfs returns this error: Error 24 : Write error : cannot write compressed block

And after that it is impossible to install a new kernel.

I don't install any kernel myself, I let the app-center take care of it. On the other hand I have to delete the old ones regularly. To do this, I use mainline.

Is this usual? Should app-center do the cleaning normally? I have always had this problem.

Thank you for your help.

  • Running into the same issue--have never manually installed a kernel, but my /boot partition is full and has stayed that way for weeks, resulting in OS update failures. I know how to delete old kernels manually, but it feels odd to have to given elementaryOS's ethos, particularly within 6 months of installing Odin.

    On my side, looks like the problem was that all kernels were marked manually installed in APT. Upstream issue looks to be this one. Fix is going out with Ubuntu 22.04 but is unlikely to be backported, so we'll probably have to wait until OS 7.
