etherpad_mypads upgrade (de 1.8.4~ynh2 à 1.9.1~ynh3) faile with the following error :

2025-09-04 19:04:52,426: ERROR - Failed to upgrade etherpad_mypads: An error occurred inside the app upgrade script

i tried to “remove” the bin and tests folders after stoping the etherpad_mypad systemd service but obviously upgrade failed anyway.

is it the upgrade script which does not clean properly the install directory before installing new sources ? is it the tar command which is not called properly (without --overwrite option) ?

is the tar error irrelevant here, if yes, why does the upgrade fail ?

what can i do ?
please help

Hummm… is a quiet old version 1.8.4…
The actual version 1.9.1 is here since few years.

Have you try yunohost app upgrade etherpad_mypads --debug --force ?

5

yes, same result

6

Ok,
Could you try upgrade to this commit ( version 1.8.18 ), first create a backup to be sure…

yunohost app upgrade etherpad_mypads -u https://github.com/YunoHost-Apps/etherpad_mypads_ynh/tree/cb3c63914a47a3b5189226737da56d915a5e002b
7

tried, same result

how does the ynh apps release system works ? I thought about upgrading first to intermediate release, but i can’t find any release nor tag on github …

8

it was the idea with 1.8.18…

Not sure is the solution…

The problem seems still the symslinks here…

Perhaps you can try this:

  • do first a backup.
  • stop the service etherpad_mypads
yunohost service stop etherpad_mypads
  • mv the files bin and tar on the folder src
mv /var/www/etherpad_mypads/bin /var/www/etherpad_mypads/src/bin
mv /var/www/etherpad_mypads/tests /var/www/etherpad_mypads/src/tests
  • recreate the symbolinks
ln -sf /var/www/etherpad_mypads/src/bin /var/www/etherpad_mypads/bin
ln -sf /var/www/etherpad_mypads/src/tests /var/www/etherpad_mypads/tests
chown  etherpad_mypads:  /var/www/etherpad_mypads/tests
chown etherpad_mypads: /var/www/etherpad_mypads/bin
chown -R etherpad_mypads: /var/www/etherpad_mypads/
  • And try do the upgrade

About the search for oldest version, it is looking for on the commits, explicitly the ones merged from testing… and then «Browse the repisotirory at this point» and read the manifest.toml where the version is edited… It can take long time…

  • I have review…

ok so now i have npm integrity error …

2025-09-07 18:56:05,342: DEBUG - npm ERR! sha1-y+vouKCHn0ypcMPWm9V44pHW6DU= integrity checksum failed when using sha1: wanted sha1-y+vouKCHn0ypcMPWm9V44pHW6DU= but got sha512-iY4+J8D+S5OP6dP9bSomJfN7zIZMcsO8h7J+EsxXod+iUpnQXmIIYsb9+Ui1Fz4KFiGbMDSaDP6Ipqz/l/1hmA== sha1-m+EdkJEyAkYaXXAYLWEDNfHAKs4=. (33035 bytes)

with both releases

i think i may be better removing the app, installing last version from scratch, restoring the db and, some how, upgrading the db. Is it doable ?

11

So,

  1. i made a backup of the app with ynh,
  2. removed the app with ynh,
  3. installed the last version from scratch with ynh,
  4. stopped the service systemctl stop etherpad_mypads,
  5. emptied the mysql db with phpmyadmin
  6. imported the old db mysql -uroot -p etherpad_mypad < backuped_db.sql
  7. restarted the app systemctl start etherpad_mypads

so far so good, everything seems to work, all my pads are alive.
