其实是个老问题了，每次 apt upgrade 都会报错，实际就是 /boot 分区分的太小，然后塞不进了就报错
当时参考https://superuser.com/questions/1601194/update-initramfs-error-24-write-error-cannot-write-compressed-block解决
先去 /boot 分区里看下老版本是啥
然后搜下”linux-image” 或者

| sudo apt list --installed | grep "5.4.0-109" (这个版本不固定，不要照抄)

理论卸掉一个 sudo apt remove linux-image-5.4.0-109-generic 就能一切继续了
你也可以一口气把老的都卸掉
