The author eventually recovered by restoring from backups onto a fresh UEFI-based VE 9 install, concluding the upgrade process itself is sound but risky for hosts with accumulated custom configuration. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### When does Proxmox VE 8 stop receiving security updates? Proxmox VE 8 loses security updates at the end of August, since it is based on Debian and follows Debian's support lifecycle. After that date the software will not self-destruct, but running public-facing services on an unsupported release means operating without vendor security backing, which pushes administrators toward upgrading to Proxmox VE 9 before the deadline. _daily.dev helps sysadmins track end-of-support deadlines before an unsupported hypervisor becomes a security risk._ ### Why did my Proxmox server lose network access after upgrading to Proxmox VE 9? Proxmox VE 9 runs on Debian 13 Trixie, whose newer systemd and udev stack can assign a different predictable network interface name to the same physical NIC than Debian 12 Bookworm did. This can make a server vanish from the network after upgrade even though the cabling and hardware are unchanged, requiring a check of interface naming in the network configuration. _developers migrating hypervisor hosts can compare real upgrade gotchas like this on daily.dev before hitting them cold._ ### Should I let apt remove the proxmox-ve package during a Proxmox upgrade? No, always decline if apt asks whether the proxmox-ve package should be removed during a Proxmox VE 8 to 9 upgrade. Removing that package can break the wider Proxmox stack due to repository drift issues encountered during the major version transition. _home lab operators planning a Proxmox upgrade can find these kinds of concrete warnings on daily.dev first._ ## Similar posts on daily.dev - [Proxmox VE 9 unlocked features I didn't know I needed for my home lab](https://daily.dev/posts/proxmox-ve-9-unlocked-features-i-didn-t-know-i-needed-for-my-home-lab-ezjbpbm6h) · XDA Developers · 1 upvotes · 0 comments - [I integrated Proxmox with Home Assistant, and my home lab manages itself now](https://daily.dev/posts/i-integrated-proxmox-with-home-assistant-and-my-home-lab-manages-itself-now-dwnc2pfhe) · XDA Developers · 0 upvotes · 0 comments - [Unscrewing lightbulbs](https://daily.dev/posts/unscrewing-lightbulbs-uyopabn02) · dbushell · 0 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#self-hosting](https://daily.dev/tags/self-hosting), [#proxmox](https://daily.dev/tags/proxmox) [View this post on daily.dev](https://daily.dev/posts/proxmox-ve-8-is-dead-in-august-but-upgrading-to-version-9-nearly-took-my-entire-home-lab-with-it-36o4dud5c) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Proxmox VE 8 is dead in August, but upgrading to version 9 nearly took my entire home lab with it","url":"https://daily.dev/posts/proxmox-ve-8-is-dead-in-august-but-upgrading-to-version-9-nearly-took-my-entire-home-lab-with-it-36o4dud5c","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/proxmox-ve-8-is-dead-in-august-but-upgrading-to-version-9-nearly-took-my-entire-home-lab-with-it-36o4dud5c"},"datePublished":"2026-08-12T16:35:06.737Z","dateModified":"2026-09-13T21:22:23.872Z","description":"A personal account of upgrading a Proxmox VE 8 home lab node to VE 9 ahead of the August end-of-life deadline, detailing multiple failure points: a boot...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/fa660ba9251c970f72e2aaf87710ecbf?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/fa660ba9251c970f72e2aaf87710ecbf?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/proxmox-ve-8-is-dead-in-august-but-upgrading-to-version-9-nearly-took-my-entire-home-lab-with-it-36o4dud5c","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,self-hosting,proxmox","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"Proxmox VE 8 is dead in August, but upgrading to version 9 nearly took my entire home lab with it"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/proxmox-ve-8-is-dead-in-august-but-upgrading-to-version-9-nearly-took-my-entire-home-lab-with-it-36o4dud5c#faq","mainEntity":[{"@type":"Question","name":"When does Proxmox VE 8 stop receiving security updates?","acceptedAnswer":{"@type":"Answer","text":"Proxmox VE 8 loses security updates at the end of August, since it is based on Debian and follows Debian's support lifecycle.
