| <p>For a change, I decided to try the do-release-upgrade script. Ugh.</p> | ||
|
|
||
| <h2>Prelims</h2> | ||
| <pre> | ||
| <code>sudo ufw allow 1022/tcp | ||
| sudo apt-install update-manager-core | ||
| </code> | ||
| </pre> | ||
|
|
||
| <h2>Run script</h2> | ||
|
|
||
| <pre><code>sudo do-release-upgrade</code></pre> | ||
|
|
||
| <p>It was at it all night and exited with error. My system is still running though, so I am not rebooting. No way. | ||
| Reading online I learn <a href="https://discourse.ubuntu.com/t/ask-ubuntu-is-flooded-with-failed-22-04-24-04-upgrade-issues/47701">many people ended without desktop and with other problems</a>, | ||
| so I spun up another terminal to drop back to ...</p> | ||
|
|
||
| <h2>The normal way</h2> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo apt-get update | ||
| sudo: unable to resolve host tardis: Name or service not known | ||
|
|
||
| nina@tardis:~$ sudo apt-get dist-upgrade | ||
| sudo: unable to resolve host tardis: Name or service not known</code></pre> | ||
|
|
||
| <p>Huh? The system lost my hostname as one of the results of the scripted attempt. Checking ...</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ $hostname | ||
| nina@tardis:~$ cat /etc/hostname | ||
| tardis | ||
| nina@tardis:~$ cat /etc/hosts | ||
| 127.0.0.1 localhost | ||
| 127.0.1.1 missy | ||
|
|
||
| # The following lines are desirable for IPv6 capable hosts | ||
| ::1 ip6-localhost ip6-loopback | ||
| fe00::0 ip6-localnet | ||
| ff00::0 ip6-mcastprefix | ||
| ff02::1 ip6-allnodes | ||
| ff02::2 ip6-allrouters</code></pre> | ||
|
|
||
| <p>Okay, add <code>127.0.0.1 tardis</code> to <code>/etc/hosts</code>, just under <code>127.0.0.1 localhost</code> in <code>/etc/hosts</code>.</p> | ||
|
|
||
| <p>And continue with:</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo apt-get dist-upgrade</code></pre> | ||
|
|
||
| <h2>Signal desktop</h2> | ||
|
|
||
| <pre><code>Err:2 https://updates.signal.org/desktop/apt xenial/main amd64 signal-desktop amd64 7.24.1 | ||
| Error reading from server - read (5: Input/output error) [IP: 172.64.155.138 443] | ||

| E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?</code></pre> | ||
|
|
||
| <p>Temporarily removed the package, fully expecting to re-install it later again when I have more time. Still runs on phone, | ||
| so not a problem, the desktop was only additional anyway.</p> | ||
|
|
||
| <h2>Chromium snap blocks</h2> | ||
|
|
||
| <p>My <code>dist-upgrade</code> process kept hanging on the chromium snap and did not move beyond it.</p> | ||
|
|
||
| <pre><code>Errors were encountered while processing: | ||
| /tmp/apt-dpkg-install-MK7qUb/000-chromium-browser_2%3a1snap1-0ubuntu2_amd64.deb | ||
| E: Sub-process /usr/bin/dpkg returned an error code (1)</code></pre> | ||
|
|
||
| <p>Trying to install it separately I got more information:</p> | ||
|
|
||
| <pre><code>The following packages have unmet dependencies. | ||
| chromium-browser-l10n : Depends: chromium-browser (>= 2:1snap1-0ubuntu2) but 1:85.0.4183.83-0ubuntu2.22.04.1 is installed</code></pre> | ||
|
|
||
| <p>I lost my temper and because I hardly ever use it, I first purged <code>chromium-browser-l10n</code>, then | ||
| <code>chromium-browser</code>, and ran the <code>dist-upgrade</code> again. Now it finally moved on.</p> | ||
|
|
||
| <h2>Python warnings</h2> | ||
|
|
||
| <p>In Python, backslashes are used to introduce special character sequences known as escape sequences. For example, | ||
| the escape sequence ' ' can represent a newline character, and '\t' a tab. But if a backslash is followed by | ||
| an invalid character, it raises a warning.</p> | ||
|
|
||
| <p>In general, a warning does not halt program execution, but it is essential to address these warnings, as they can | ||
| indicate potential issues with the code. Ignoring these warnings can lead to unintended consequences, such as | ||
| incorrect string formatting, unexpected behaviour, or even security vulnerabilities.</p> | ||
|

||
| <p>I encountered these, you will encounter yours:</p> | ||

| <h3>Upgrading PostgreSQL</h3> | ||
|
|
||
| <p>Okay, this one is normal after a major PostgreSQL upgrade.</p> | ||
|
|
||
| <pre><code> | ||
| Creating new PostgreSQL cluster 16/main ... | ||
| /usr/lib/postgresql/16/bin/initdb -D /var/lib/postgresql/16/main --auth-local pe | ||
| er --auth-host scram-sha-256 --no-instructions | ||
| The files belonging to this database system will be owned by user "postgres". | ||
| This user must also own the server process. | ||
|
|
||
| The database cluster will be initialized with this locale configuration: | ||
| provider: libc | ||
| LC_COLLATE: en_US.UTF-8 | ||
| LC_CTYPE: en_US.UTF-8 | ||
| LC_MESSAGES: en_US.UTF-8 | ||
| LC_MONETARY: fr_FR.UTF-8 | ||
| LC_NUMERIC: fr_FR.UTF-8 | ||
| LC_TIME: fr_FR.UTF-8 | ||
| The default database encoding has accordingly been set to "UTF8". | ||
| The default text search configuration will be set to "english". | ||
|
|
||
| Data page checksums are disabled. | ||

|
|
||
| <p>That is, of course, <a href="https://www.postgresql.org/docs/current/upgrading.html">not the end of the story</a>. | ||
| Been there, done that several times already, ate the t-shirts. Did not upgrade from 14 to 15 yet even.</p> | ||
|
|
||
| <p>Now the current clusters will have two version of postgresql, in my case 14 and 16 because I could not be bothered to do the data upgrade to 15:</p> | ||
|

| </code></pre> | ||
|
|
||
| <p>Stop the new version:</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo pg_dropcluster 16 main --stop</code></pre> | ||
|
|
||
| <p>Start the upgrade process:</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo pg_upgradecluster 14 main</code></pre> | ||
|
|
||
| <p>Monitor the process, and when done without problems, remove the old version:</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo pg_dropcluster 14 main</code></pre> | ||
|
|
||
| <p>Purge the old package:</p> | ||
|
|
||
| <pre><code>nina@tardis:~$ sudo apt purge postgresql-14 postgresql-client-14</code></pre> | ||
|
|
||
| <p>Double-check the current clusters:</p> | ||
