First check if your CPU is really 32 bit. You may be running a 32 bit version of Ubuntu in a 64 bit CPU, and then you can install a 64 bit version of Ubuntu on this.
Run the command lscpu
and look for CPU op-mode(s):
. If the output is 32 bit, 64 bit
, you can fresh install a recent, 64 bit version of Ubuntu/Xubuntu/Lubuntu on this computer (the last two need less resources). If it is 32 bit
, head on to the next part of the answer.
Ubuntu does not support i386 architecture (which is 32 bit) beyond version 19.04. If you want to continue using a recent operating system with updated packages, you will have to migrate to a different operating system. You have several options.
- Debian i386 -- Debian is very similar to Ubuntu. You can install the LXDE or XFCE desktop environments, which are lightweight.
- Q4OS -- Debian based OS, optimized for older computers. The Trinity desktop environment (actively maintained fork of KDE 3.5) requires only 128 MB RAM, and is super fast.
- MX Linux -- Debian based distro tailored for old computers.
- Arch Linux 32 -- Hard to install, but can be made extremely lightweight, and it hosts the latest version of packages in its repositories.
- Tiny Core -- Extremely light weight operating system, which works on systems with 48 MB RAM or greater.
Note: None of these operating systems are supported on this site.
