Mail app

**Mail app version: 0.7.7

Nextcloud version: 12.0.4
Debian Jessie
Apache/2.4.10 (Debian)
PHP Version: 5.6.33
mysql Version: 5.5.58

Useragent : Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0

[ChristophWurst]

Do you know which version had been installed before?

[lepool]

Sorry, im think the 0.7.6, but im not sure. It was an automatic update notice from Nextcloudsytem.

[lepool]

How can i downgrade the mail app? If i delete the mail folder and install the older version then the system install every the new 0.7.7 with the issue.

[ChristophWurst]

Downgrades are not supported, sorry.

Please enable debug mode and post your nextcloud.log and horde_imap.log here (only the last entries are relevant). This should allow me to identify the issue.

Thanks.

[ChristophWurst]

Also please check out the network tab on your browser's console. Would be interesting if there's a HTTP 500 status code on one of the requests. If so, please take a screenshot of that.

[ChristophWurst]

Btw, nice avatar! :)

I have changed the email addresses to preserve spams

[ChristophWurst]

Class 'Kwi\UrlLinker' not found at /var/www/https/cloud/apps/mail/lib/Service/Html.php

How did you install the app? Did you use a git clone or a package from apps.nextcloud.com?

[ChristophWurst]

"Exception":"OCP\AppFramework\QueryException","Message":"Could not resolve appName! Class appName does not exist"

This is a pretty bad one. The dependency injection container cannot resolve a class. Unfortunately, the stack trace does not tell us which class it failed to resolve.

[lepool]

I deleted the contents of the mail folder and then copied the app mail 0.7.6 to the mail directory

[lepool]

here the error in browser-console

and then copied the app mail 0.7.6

Where did you get the app from?

[lepool]

https://github.com/nextcloud/mail/releases/download/v0.7.6/mail.tar.gz

[lepool]

An attempt to login via another user on the nextcloud now permit to preview the mail. But only the other user. The account admin can't preview mails ..

[lepool]

Strange things :-|

[lepool]

On the other account only the HTML mails can be viewed !

[lepool]

I confirm, HTML mails can be viewed on all accounts, text mails not .

PHP Fatal error: Class 'Kwi\UrlLinker' not found in /var/www/https/cloud/apps/mail/lib/Service/Html.php on line 64

[Bables55]

I also had the same problem. Text based mail can not be opened. No error log is generated at this time. I was getting an error when updating from 0.7.6 to 0.7.7. It looked like MySQL. I tried deleting the mail account and reinstalling the Mail application but it did not improve. This seems to be a problem specific to 0.7.7.

Error log that occurred during update.

There is no error log of mail other than this.
You think to me that it is not recommended. However, I could display text-mail when I returned to 0.7.6.

[joergmschulz]

same here / on my test system I had 7.6 working fine, then had the app-store upgrade to 7.7 and no txt msgs are visible any longer.
If needed I could delete the app and the tables completely and test with a fresh install (just to exclude an upgrade issue).

[Kugeleis]

same here 7.6 worked, 7.7 can't only show html mail. Loading inbox takes ages.

[lepool]

on th nightly build the issue aren't present :+1:

[moonwolf-github]

Cool, as this also kicked me.

[foxbow]

Sorry for the stray reference. But I also do not see text emails, only HTML encoded ones after updating from 0.7.5 to 0.7.7 but can confirm that the nightly build fixes the issue.

[ChristophWurst]

on th nightly build the issue aren't present 👍

Now that is quite a surprise. 0.7.7 and the latest nightly on the app store effectively point to the very same archive: https://apps.nextcloud.com/apps/mail (just compare the URLs, they both point to https://github.com/nextcloud/mail/releases/download/v0.7.7/mail.tar.gz).

[foxbow]

I was not using the App store but downloaded and installed the tarball from the host mentioned in the developer docs.

[ChristophWurst]

Thanks for that info. I'll compare the nightly build and the one on the app store. Maybe I've made an error during packaging the app.

Sorry for the inconvenience meanwhile. I won't have time to look into this before Monday, but it'll definitely try to fix this ASAP.

Although I know it's not a solution for many of you, but the app seems to work fine with Nextcloud 13, which is in RC right now. So if anybody is eager to try out the upcoming Nextcloud 13, you could upgrade to it meanwhile.

[aspseka]

Not true. Same problem here, cannot find Class 'Kwi\UrlLinker' while trying to open text-only mails. On Nextcloud 13b3. Installed via app store.

Directory contents in (nextcloud)/apps/mail match those of https://github.com/nextcloud/mail/releases/download/v0.7.7/mail.tar.gz , save one .htaccess file.
Path issue?

[brunt82]

Nightly build makes no difference: in both cases I get the same error message:

@nickvergessen @rullzer I've made a suspicious observation. If I install composer deps with composer install, the Kwi/Urllinker class is not a member of composer's class map. However, if I install with composer install -o, it's there.

Have you ever seen anything like that?

As a hotfix I'll change the packaging script and re-publish a release. But it would be great to know why it's failing without the -o flag. This feels like a composer bug. The lib has been used for three years and now it's apparently the first time this causes problems.

[ChristophWurst]

If someone could help me verify this new package works: mail.tar.gz - that would be great 😀

Will publish a release as soon as someone approves the hotfix.

[moonwolf-github]

Works for me! :D Nextcloud 12.0.4.

[joergmschulz]

Matching your expectations, the mail.tar.gz you provided works in my test environment AS OPPOSED to the 7.7 version from the store. ED: NC 12.0.4

[brunt82]

Also works for me.

[ahobitt]

@ChristophWurst Thank you! It works for me too.

[Gomez]

Works here!

[ChristophWurst]

You're awesome! Thanks to the quick feedback ❤️
