16	16

20	20
21	21		## Ubuntu 11.10 (Oneiric Ocelot)
22	22
23	23		### What you want
24	24
25	25		Matching versions of Lazarus and Free Pascal are in the repository (20/02/12). They are
26	26
27	27		- Lazarus 0.9.30-2.
28	28		- Free Pascal 2.4.4
29	29
30	30		In Synaptic they are called Lazarus 0.9.30-2Build1, fpc, and fp.
31	31
32	32		### Find and install the packages
33	33
34	34		In the Software Centre search for and install:
35	35
36	36		- IDE for FreePascal - SDK metapackage - search under lazarus
