[Ubuntu Claims vs Evidence](https://www.g2.com/products/ubuntu/claims-vs-evidence) # Ubuntu Claims vs Evidence G2 compares Ubuntu marketing claims from the sources linked below with real user reviews, then assesses how strongly the review evidence supports each claim. Last updated Sep 30, 2026 ## Claim: “Chiseled images cut footprint and quicken start-up, while Ubuntu Pro delivers CVE fixes and support for production grade security.” Mixed support from reviews. Reviewers provide relevant support for Ubuntu Pro’s extended security coverage and support, while reports on lightweight performance and startup speed are mixed. The reviews do not specifically establish that chiseled images deliver the claimed footprint and startup improvements. - “the predictability of the 5-year support cycle (extendable to 12 years with Pro)” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/8838775) - “The most significant benefit of migrating to Ubuntu, its simplicity and performance. Ubuntu is far lighter than Windows etc. OS, resulting in faster boot times.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/12659622) - “slow startup times and sometimes taking up unnecessary storage” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/12580339) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “Livepatch offers a rebootless security patching automation to address high and critical kernel vulnerabilities that surface between scheduled maintenance windows.” Mixed support from reviews. Reviewers are split: one reviewer could not set up Canonical Livepatch despite several attempts, while another reports ease of installation and updates involving Livepatch. The reviews do not specifically establish rebootless patching for high or critical kernel vulnerabilities between maintenance windows. - “Despite several attempts, we could not set up the Canonical Livepatch service during installation.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/7388086) - “ease of installation, update (livepatch, landscape or not).” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/11179725) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “Expanded Security Maintenance (ESM) provides 10 years of vulnerability fixes for critical, high and selected medium vulnerabilities across the whole Ubuntu archive, as defined by Ubuntu Priority.” Supported by reviews. Reviewers generally report extended security support and vulnerability fixes, consistent with the claim’s direction. However, the reviews do not establish the specific 10-year duration or the full scope of vulnerability priorities and archive coverage stated in the claim. - “Ubuntu pro offered extended security Maintainace” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/9036858) - “there is still support option for especially security vulnerabilities.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/3341828) - “Ubuntu is very good at shipping security vulnerability fixes” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/9495705) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “Enable management at scale with staggered updates, asset inventory, hardening, and audit functions for data centers, workstations, and IoT devices.” Mixed support from reviews. Reviewers cite Landscape, extended security/compliance, and automatic patch management as support for centralized maintenance and security administration. However, another reviewer reports incompatibility with enterprise MDM and difficulty deploying and managing Ubuntu remotely, so the broader scale-management claim is mixed. - “landscape is a terrific product especially if combined with a remote access web” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/11179725) - “Recently, I noticed an automatic update and patch management system that makes system maintenance easier.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/9721169) - “Ubuntu does not work or is not compatible with our main MDM systems. It's hard to deploy and manage remotely. The permissions for enterprise are complicated.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/12700536) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “Ubuntu Pro extends the life of every Ubuntu LTS from 5 years of standard security maintenance for the Main repository to 10 years for the entire Ubuntu Archive (Main and Universe repositories).” Mixed support from reviews. Reviewers provide support for Ubuntu Pro offering extended security maintenance, but the reviews do not establish the claim’s specific 10-year coverage. One reviewer instead describes the support cycle as extendable to 12 years with Pro, which conflicts with the stated magnitude. - “predictability of the 5-year support cycle (extendable to 12 years with Pro)” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/8838775) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “Existing Ubuntu LTS systems can be upgraded in-place to Ubuntu Pro without redeployment, streamlining the process across large Ubuntu estates with a single command.” Supported by reviews. A reviewer explicitly reports that Ubuntu can be upgraded to Ubuntu Pro, supporting the core upgrade capability. However, the reviews do not independently establish the specific in-place, single-command process across existing LTS estates. - “If you need more enterprise-focused use, you can also upgrade to Ubuntu Pro.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/12704608) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro) ## Claim: “With the Legacy add-on, this is extended an additional 5 years, giving you a 15 year security maintenance and support commitment.” Mixed support from reviews. Reviewers provide mixed evidence: one describes a 5-year support cycle extendable to 12 years, which conflicts with the claimed 15-year commitment, while others mention extended security maintenance or support through 2036 without establishing the specific 15-year duration. - “the long-term support until 2036 offers peace of mind for stability and updates.” [Read Full Review](https://www.g2.com/products/ubuntu/reviews/10335295) Source: [https://ubuntu.com/pro](https://ubuntu.com/pro)
