I am currently trying to install Lubuntu 20.04.2 LTS on a low-spec laptop (2 GB RAM, 30 GB SSD). I am finding the partition stage quite tricky to get it to work, as it keeps complaining about the EFI partition. The instructions in the Lubuntu installation manual are lacking in detail and all of the Q's & A's on this site and elsewhere on the web do not tell me what I need to know to get it working. After some trial and error, I came up with the following, which allowed me to get Lubuntu installed but is still wrong because /boot is FAT32 so fails on kernel upgrades:
Type | Size | Mount point | Flags |
---|---|---|---|
linuxswap | 2 GB | n/a | swap |
FAT32 | 512 MB | /boot | boot |
FAT32 | 512 MB | /boot/efi | boot, bios-grub |
ext4 | the rest | / |
As I say, the above installed but then failed on kernel upgrade.
I am currently trying the same as above but with /boot as ext4. But I'm still asking this question as it may or may not work and even the above might help some people.
So, questions:
The above is done with MBR partition table rather than GPT. Is that OK?
Is it necessary to have separate /boot, /boot/efi and / partitions? I would happily just have swap and / but the installer complains about efi so fair enough I can add /boot/efi but do I really need /boot as well? From trial and error it looks like maybe yes but I would rather do without it if possible.
Are the above file system types and flags correct (with /boot changed to ext4)? Just because the trial and error feedback loop is slow.
Thanks
