−## Limited support operating systems
103
−
104
−The operating system versions listed in this section currently have **limited support**. Newer agent versions won't support these operating systems. The last agent version that supports the operating system is listed, and newer agent releases won't be made available for that system.
105
−
106
−The listed version is supported on the specified agent version until the **End of Arc support date**. If critical security issues are identified that affect these agent versions, the fixes can be backported to the last supported version. However, those versions won't be updated with new functionality or other bug fixes.
107

108
−| Operating system | Last supported agent version | End of Arc support date | Notes |
109
−|--|--|--|--|

−| SUSE Linux Enterprise Server (SLES) 15 SP3 | 1.58 | 07/03/2026 | |

−### Connect new limited support servers
114
−
115
−To connect a new server running a limited support operating system to Azure Arc, you may need to make adjustments to the onboarding script.
116
−
117
−For Windows, modify the installation script to specify the version required, using the -AltDownload parameter.
118
−
119
−Instead of the standard command:
120
−
121
−```powershell
122
− # Install the hybrid agent
123
− & "$env:TEMP\install_windows_azcmagent.ps1";
124
−```
125
−
126
−Use the following command, replacing the URL with the one for the last supported agent version:
127
−
128
−```powershell
129
− # Install the hybrid agent
130
− & "$env:TEMP\install_windows_azcmagent.ps1" -AltDownload https://aka.ms/AzureConnectedMachineAgent-1.39;
131
−```
132
−
133
−For Linux, the relevant package repository will only contain releases that are applicable, so no special considerations are required.
