Everything is up to date as regards versions, at least as far as I am aware, as I run global updates every few days.<br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;">I am having a problem with the <span style="font-variant-ligatures: no-common-ligatures;">isc-kea-dhcp4-server.service. Whenever there is a system reboot, this service fails to start. When I manually restart it later, it works fine. As far as I can trace, it's a startup sequence issue in relation to having MariaDB as a back-end for Kea. I looks like Kea is starting first, looking for the MariaDB service and failing because MariaDB has yet to start.</span><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><span style="font-variant-ligatures: no-common-ligatures;">How can I change the start order so that<span class="Apple-converted-space"> </span></span>the <span style="font-variant-ligatures: no-common-ligatures;">isc-kea-dhcp4-server.service doesn't start until the MariaDB service is up and running?</span><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><span style="font-variant-ligatures: no-common-ligatures;">I expect I will have the same issue with the isc-kea-dhcp6-server.service when I eventually start to use it.</span><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><span style="font-variant-ligatures: no-common-ligatures;">Thank you,</span><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><br></div><div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: SFUIText, Helvetica, sans-serif; font-size: 17px; font-style: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: -0.3700000047683716px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none;"><span style="font-variant-ligatures: no-common-ligatures;">PeterP.</span><br></div></div></body></html>
